I have a '98 2500 4x4 with a 360 that is in pretty rough shape. I have found a '99 1500 2wd with a 318 that has 50k miles on it but has been hit in the front end. What I would like to do is replace the cab and bed on my truck with the '99 and possibly use the 318 as well. My concern is what issues will I run into as far as the computer and trans difference? Thank you in advance for any help.
