Mustang Subframe Connectors On T-bird/Cougar?

[FONT="Arial"][SIZE="2"][/SIZE][/FONT]I'm doing a chassis restoration on my '87 T-bird and looking for some subframes.

I've heard you can use Mustang frame connectors, if so;

Will Edelbrock Subframe #5291 fit on T-bird/Cougar?    

Thanks!

T-Birds and Cougars don't need Mustang subframe connectors. It's a flat plane between the front and rear frame rails, and you can use rectangular tubing (I think it was 1" X 2" but not sure). The seat-support-cross-brace thingies aren't difficult to make either (Chuck W used to sell some I think, but not sure if he still does)

I'd think Mustang connectors would be too short.

I copied this from Erics site, I wonder if you called Maxmotorsports if they could advise you?

Subframe Connectors
The steel bars known as subframe connectors are excellent for helping to keep your underside together. They connect the points in the unibody "framerail" that are severed in production. Weld-on types are the most effective (while also being race-legal) and should be the only types considered. Bolt-ons will only create elongated holes with time. Maximum Motorsports makes subframe connectors for the Fox Thunderbird/Cougar. People have also reported that Mustang units do indeed fit on the Fox Cougar, so you can probably use these as well. Or you can have custom pieces made for relatively cheap. After installation, you'll have to paint up all the welds so they don't rust.

I used the cheap Summit Mustang ones, but they needed to be bent a little straighter than how they came.

No need to buy Mustang SFCs, since they don't work properly on the Tbirds/Cougars anyway.  Buy 10-12' of steel ($30-40) and make your own.

Is it "really" beneficial to do the seat crossbrace piece?  Or just weld up the 2 subframes?

i have a set of kenny brown subfame conecters in my 87 5.0 tbird. they are longer than mustang ones and straighter.  what kind did you want to do weld in or bolt in? its better to go with weld in but u have to have a drive on lift or a pit to use to put them on or you will weld in a twist.  i wouldnt see any reason not to make them your self and the seat brace is there to get rid of flex by tieing into more parts of the car. if you did ones without seat bracese it would still flex a bit but not as much

You'll have to cut the floor in the rear

 No, the KB ones are not longer than the Mustang ones.  How do I know?  I initiated the production of them, and I was limited on length by the racks we sent parts to the platers with.  They are straight pieces of steel though, with no bends like the Mustang ones.  If I'd had my way, they would've been at least 5' long, instead of 4'.

On the seat brace, fab something up.  It's beneficial.

I see a  on the back end that's not in the drawing is it self explanatory when mocking it up? And Chuck do you still make the seat reinforcements at 6'6" 310 lbs I'm gonna need help with the floor someday?

Thanks Again
