I have a J body. Love the way it drives.
I have a 2003 Dakota and love the way it drives MORE! lol

I think though not positive the last 1957 Plymouth I looked at.... he WELDED the front structure in. Didn't bolt it in. Strange but true.

Dakota front clip isn't much harder IMO, and the only options that worry me are the stock setup with Volare spindles. I just worry about the 57 front end, steering and steering box. I don't mind buying bushings, ball joints, steering stuff etc but I want a comfortable 90mph cruiser.....
