I want to install a new front end in my 1931 plymouth. i currently have a corvair in there.
i know fatman makes a setup for this but i can get a much better deal on the camaro front end.
has anyone done the camaro setup?  if so what problems did you encounter? any help/concerns would be appreciated.  

Even if you can get a good Camaro/Nova subframe clip for free, I don't think it would be a good swap on your '31 Plymouth. If you want independent front suspension, a Fatman or other good quality Mustang II setup is the way to go.
Unless you're building the car as a fenderless Hiboy, there's no way to hang the stock front fenders and other sheetmetal on the Camaro clip.
I don't have direct experience with a '31 Plymouth, but I know the frame is not much wider than a Model A Ford.  The Camaro clip is going to be a lot wider than the Plymouth frame, and I don't see how you could mate the Camaro clip to the Plymouth frame without it looking cobbled together and potentially being unsafe.  Another issue to think about is title/registration issues. I don't know where the serial number is on a '31 Plymouth, but old Fords and a lot of other old cars only have the number stamped on the frame with no serial number tag anywhere on the body. If you saw off the front end of the frame and that happens to be where the serial number is on it, it could seriously complicate title/registration issues, moreso in some states than in others.  

lamar,
    Thanks for the info. i definitely want to be safer than sorry. i am glad i asked before i got that front end. this is a good forum and for being a newbie it is very helpful. again thanks  

Lamar is right, install a MII style. Not to talk againest Fatman, but there are a lot of mfgs. that make frnt. end kits ao do your homework and good luck.
