Were working on filling in the Info on the spreadsheet. If your endeavors come accost any more that’s not there please share.

We do measure the 84 Mark axels as longer than the TC by .56 (.002 under 9/16, less than the thickness of a sheet of notebook paper that measures .003) But your looking at later Mark Axels. May or may not be the same.

As far as longer Mark axels not working…
I do know as far as changing axel in the housing, the Axel Length is somewhat irrelevant. I have 30.47 Mark axels in a 90 Mustang housing where 29.18 axels came out of. What matters in them fitting is the “spline to bearing race” measurement. This is the same on both these axels I mention. However, the overall width of the assembled rear is larger.

The 84 Mark Housing is the same width as the 90 Mustang housing

I know what hub your talking about, and I can supply that info for these three axels (I have them) if it will help you
84 Mark VII 5 lug
88 Tbird 4 lug
90 Mustang 4 lug
I'll measure my Mark Hubs this evening.

But would longer axles not interfere with them staying in the housing properly(side to side play)?????
If the mark axles are only a sheet of paper longer than the TC axles would they not line up the brakes quite nicely, .003" should not make any real differance in lining them up should it????
Really the problem with the TC rear axle is the brakes, as other axles due not put the rear rotors inline with the caliper mounts correct???
Mark axles should work as cougarman suggested.
If the mark axles do indeed work is the bearing diameter the same between the TC and the mark axles????
If so in theory the abs rings should press off the mark axles and the tc ones should presson in there place given the .003" paper thin differance.
As for hub size this is most important as this decides weather the tc rear rotors fit correctly.
My hub size on my 87tc measures 2 1/2"(hard to measure with the wheel on there but sure looks 2 1/2" on the tape).
The axle i use needs also to be 2 1/2" to use the TC rear rotors so the mark axle is really the only measurement i need jim.
The bird axle and stang axle have to be 2 1/2" because i'm running 93 pony wheels right now and i ran them on my old 88bird with the 7.5" rear and the center hub of the wheels is/was perfect to the axle hubs.

Let me settle this. I was going to be selfish, and keep the information to myself, but Ill let it all out.

Use 91-92 Mark VII axles, axle end brackets, ABS sensors and rotors, then use your TC calipers, slider brackets, lines, and e-brake cables. Problem solved. You keep your ABS.

Your wheels will be pushed out 1/2" per side, buy by using the rotor, exle end brackets, and axles, it works properly.

TC rear with 84 Mark axles, caliper brackets. rotors,and calipers, I didn't keep the abs though. :D

K i checked the bearing part #s for the mark rear 8.8 and tc rear 8.8 and they are the same so that solves that,the axle diameter is the same.
Now cougarman let me get this straight you used an 87-88 tc rear axle, put 84 mark vii axle shafts in it and used what year of rear mark rotors and calipers???
What size axle hub is that at the end there????
Did the tc caliper mounts on the axle work with the mark calipers or did you have to knock off the old ones and weld on new ones?????
If you had a 5lug tc rotor would it line up with it's own caliper mount with those axles???
Are the tc and the mark rotors the same depth in a side by side comparison,i know they are bigger around but what about depth where they mount to the axle????

[/COLOR][/COLOR]Nope, they are held in by a C-clip at the Ring gear end of the Axel, they could be 20feet long and still stay in there (wouldn’t advise trying to mount 20ft long axels in there!)

Sorry, you miss understood me or I was unclear, they are "almost" 9/16 different in length (almost= actualy .002 short of 9/16)

See above about the .003 (ignore the .003! I should not have mentioned that it’s just confusing you.. the value is .562= 9/16)

I’ll measure the hub tonight. It may be a bit late and a brief message on the Diameter as I have to run to the Home site to check some things tonight (last minute changes to my pump house design needed to be gone over) I’ll do it as soon as I get home.

Thanks jim that makes more sense.

232 that all sounds good and i apreciate the info however pushing the track out 1/2 per side won't work as i'm already worried about using 18x10s in the rear with a 27mm offset and that would push them out past the fender wells.
Did you have to knock the tc caliper mounts off and weld on the mark ones,don't want to change my rear end like that either want to try and use tc stuff(keep it very stock appering and tracking).

You know what i've found the solution,simplilist and cheapest way to keep everything the way i want(abs,trackwidth etc) and on the cheap.
I'm gonna pull my axles and send them to the machine shop.
Have the 4 lug pattern welded up and machined flat then have them redrilled and studded 5x4.5" lug pattern,axle problem solved and they look like they came that way.
Next the rear rotors,well just got thru talking again with the idiots at j2parts and they absolutley will not ship to canada no matter mow much i pay for shipping so my custom 5lug TC rotors are out the window,they didn't sound all that bright anyways and i'm sure would send me honda rotors or something.
The rotors will also be welded up and redrilled 5x4.5",this way all will fit and work perfectly,no hassles and will cost me the same as if i was to get custom rotors and new axles,probably cheaper.
This just seems to be the only solution to do what i want and i want it like stock appering.
Thanks for all the info guys and sorry about gettin everyone's hopes up to a 5lug abs TC solution,this will be my solution,pics will come when done in a month or so.

Dominator
Hub size on my 1984 Mark VII rear axels is 2-3/4
I checked, ReChecked, Checked my Mustang axels (2.50 FREAKED OUT :eek: becouse I just spent $600 today to get tires mounted on those Mustang Bullitts I'm planning on putting on these axels, test Mounted my Bullitts Heavy Sigh they fit, snugly)

again (now that I went off on a tangent)

Dominator- I have 88 LSC axles, rotors, calipers and ABS on my 87 TC. No problems with fit or spacing.

How did that work,you used the axles rotors and calipers off of the mark????
Did the caliper mounts bolt right up to the tc brake mounts on the axle????
Did it not push your rear wheels out 1/2" per side???

I did have to grind off the anti-moan brace is on the TC rear, but the 91-92 Lincolns dont use a brace or bracket. The mounting bracket is actually thicker than that of the TC, so they didnt use the anti-moan brace.

I wish i had pictures from my build.

I'm putting the same as Tommym on my 88 Dominator.
91 Mustang 8.8 housing and gears.
1984 Lincoln Mark VII Axels, Rotors, and calipers.
and I don't expect any problems with fit.
First 1/2 isn’t much
Aside from that overall Axel width is not the only thing that matters.

My original 4-Lug 14” wheels have a 5” backspacing
The new 5-Lug 17x9 wheels I’m putting on have a 6” backspacing.
This adds up to actually 1” narrower if measured on the Inside of the tire even though the axel is 1” wider.

So while my overall axel is 1” wider (1/2 per side) the inside of the tires between the wheel wells (what counts the most) will only be 1” narrower, ½ per side.

I measure my existing tires and come up with 1-1/2 inch clearance on the inside tire to body per side. This set up should take that down to 1” and that should be fine.
Then I measure 12” MAX allowable tire width till I hit the outer fender. The Tires I bought are 275/40/17 If I remember right there about 11.5 wide

Sweet as pie!! IN THEORY: This is not actually installed yet!

The axles, calipers and rotors are from the 88 Mark. It was done by the guy I bought the car from. I just replaced the calipers on the rear and the ones I bought are for a Mark. From checking the rear end my rims are inside the top inside lip of the fender. I have 17x9 Cobra rims with 245/45ZR17 Goodyear F1's.

Appreciate the info but when you figure how much new rotors,calipers,brake pads and used axles cost,you can send your Tc axles and rotors to moser and have them both filled and redrilled for 85 for the axles and 60 for the rotors+shipping of course but this way they are guaranteed to work without any issues.
