i know there is a 2.5" difference in wheelbase, but i assume this could be taken care of with zero rates. but where would you want to move the axels? more up front or more in the rear, i've been told not to use the zero rates at all, and to center the rear wheel and let the front be moved forward the difference to keep the rear of the front tire out of the firewall.?? the frame rails are the same width, so i'm not all that concerned about moving the body mounts, as i plan on filling all the unused holes in the frame and also boxing the frame,(so moving body mounts doesn't seem that hard) my main goal is to strengthen it where the leaf springs attach. and make the bottom as slick as the paint on the body so when it comes out of the mud pit, i can get it mostly clean by using their fire hose in the clean up area. what other obstacles can i expect. i have a full on machine shop at my disposal. but any help from people who have done this would be greatly appreciated.
