I don't have a donor vehicle yet. I'm just trying to gather enough information to choose the correct donor to get everything that I want with the least amount of time and money involved if I do decide to make the swap. According to information that I've received, 94 and newer frames pose additional problems due to a rise in the rear frame rail. Can you enlighten me on what problems I would have to overcome if I used a 94 or newer donor? I would really like to go 04 or newer to be able to get into a Hemi donor vehicle. I do realize that the frame would have to be shortened with anything 94 and newer. Also, are there any track width issues, or frame width with the newer vehicles? Did the frames ever differ in width, throughout the years?
