I am debating whether or not to use a 1974 firebird subframe in my 41 Plymouth. Any info available ? I see a lot on Ford or Chevy but not much on Chrysler products.

I would go for it!

Modern brakes and steering on an old car are safer. The simple fact is that you will be driving with newer cars that can stop much faster than your 1941 technology.

I would look into the width of the sub-frame from brake face to brake face. You need to see if it will fit under your car and still have room to use the wheels you want to use. It still has to look good!

It is most likely that you will want to spec your wheels with the offset that looks the best. That in mind, if your sub-frame is too large than your wheel back space will force you to go with a shallow wheel. You have to see if you like that look.

I think the Mustangs IFS has a smaller width than the Firebird.

With the new kits out there you can buy a disk brake conversion with the bearings. Fat Man makes a kit to install a rack and pinnion that I put in mine that works great.
Mine was built prior to the availability of the kits, so I cut off the spindles and made an adapter and then bolted on AMC rotors. I seen this on another car and it worked great. Also put a bracket on the frame and put on longer shocks. Hope this helps you with some options.

I have said this before. If you don't all ready have the fire bird front end or can get it real cheap. Look for a 70's, 80's new yorker or diplomat. You can find them cheap w/ V8's,disc brakes,auto and a rear end. Ford for a Ford, Dodge for a Dodge, Chevy for a Chevy.That is just my .02 cents.
