I was looking at my history 999 report today when I noticed something that didn't make sense...yet I'm hoping is true :D
According to Cool Cats, these cars should have come with a 2.73 gear?

What rear does it have now? I just called for the Sport's report.They said they'd call me within two business days,then I can have them mail or email the report.We'll see what happens.
The 86 Cougar XR7 Turbo i just parted out had a 3.45 tracloc rear in it. It was a 7.5in though.
Yes but I thought all the V-8 models were 2.73. You need to crawl under the car and look for yourself.

Yea I believe standard for a 5.0 was 2.73s....and then 3.08s were optional. Or *maybe* 3.27s, if I remember correctly from coolcats, 87 and 88 the 5.0 XR7s could have a 3.27 trac-lok if ordered that way.
3.45's were only for the Turbo 4 cars
One way for sure to tell is, jack the rear end up and turn the tire 1 revolution and count how many times the driveshaft makes complete rotations. About 3.5 times would be your answer.
^^^^^^^^^^^^^^^^
and certain 5.0 84 elans :rollin:
Dealer option?????
How odd would that be if that were true! How could Ford screw that up on a report??
Well, the sticker on my door jamb says I have a locking 3.08 axle. I think I'll do what mcb said, just for the hell of it. It is a 7.5" by looking at the shape.
Stranger things have happened , I owned a vintage Mustang once with two different VIN stampings one above the other on the inner fender .
That was a pretty common occurance. Those vins were hand stamped on the assembly line. It seemed to happen at the Dearborn facility more than anywhere else.
Unless it was a mandated factory modification, the 999 report would not show any dealer changes(doubtful even then)...
Just goes to show, don't believe everything you see...
That's what I meant. Maybe the dealership actually did a special order for one for some reason? I would guess stranger things happened....
AFAIK the 3:45 wasn't available for order on a 5.0 for any reason, I believe the combo would have had to be smog certified...
Anyway the data tag calls out a 3.08, just another Ford screw up...
One of my cousins worked at the Norfolk Assembly(now closed), on a tour for myself and a friend in '94 he said his son wanted a certain axle ratio in his truck but wasn't available, I said "Lee you can't fix that"??? He said "nope parts are ID and loaded on the assembly line by Job/VIN number, and besides the supporting plants only ship parts in after the vehicles order number was received in the front office... A axle assly would have to be mis-marked at the plant that mfg'd it to be incorrectly installed...
Would it have been the same 10 years earlier though?
Probably.
Is it worth it to point out this discrepancy to the people who do the 999 report?
Refer to the information here please...

Should help you figure it out.
History 999 reports are known to be wrong sometimes. I've seen incorrect axle ratios before on them.
