    Cadillac Rear End

    I posted on here before about how I am putting a Cadillac 500 in a 65 Mustang and we are making good progress on the project but I have a few questions about the rear end, first is it possible to shorten the Cadillac rearend, I have a 75 CDV, and if it is possible would it be reasonable to do this or would it be better to just get a rear end that fits my car? I don't know what the gear ratio in the Cadillac is, so if someone knows, would that same ratio work for the Mustang or would I have to use something different? Thanks in advance.

    You have the choice of rear ends. Is the 69 leaf or coil? The Fox body 8.8 is strong and inexpensive and I think it goes in the early Mustangs fairly well. A major question is width. If you can find something close in width it's a lot cheaper than having one narrowed.

    I find it odd that you are capable of an engine swap and dont know about narrowing a rear end? To your point, I would find an early Lincoln Versaille rear end. Its a nine inch to handle the torque,
    Ford bolt circle and has disc brakes as well. If your check book can handle it, you can modify anything.

    You can get a 9 inch rear end built for anything but.....I think I read once that Ford Rangers had 8.8's and leaf springs making it a popular hot rod swap.

    I have a 1947 Cadillac and want to change out the rear end which is on leaf spring and place air suspension

    You'll never get a reply to a thread that has been dead for 6 years, and your question has nothing to do with engines. As soon as you show site activity again, I'll move this to the proper Classic Cadillac forum.
