I have an 83 CGT that was recently wrecked. I am currently looking at an 86 CGT. How much parts interchageability will be viable. Or to take another direction, what kind of problems will I encounter if I try to put the I-5 into FWD 84 4KS. Any thoughts on either topic will be appreciated. Gary Meier 84 4KS - 88 5KSQ
