I am looking at 2 K5s tomorrow and ones an 88K5 350 TBI auto 4"inch lift 33x12.5x15 Black with maroon interior owner says one rust spot on bottom of door thats it 3500.obo Probably more rust but I will find it if it is there. the other is a 90 K5 Again owner says no rust. Brand new 8" Superlift brand new 36" tires and new wheels, Blue 350 TBI auto. Now here is the kicker replaced stock 10 bolt in rear with a 12 bolt 4.10 but front is geared something else so can't put in 4 wheel. He says everything is mechanically perfect and power everything. He has lost interest in it when it got hit on the drivers side and needs new door and bedside just body damage he wants 4300.00 obo it started out at 5500.00 about a month ago. He says tires and lift only have a 1000 miles on it when it got hit. What do you think it will cost to get the bedside replaced and I already have new door that I had for my other K5. What would the gear change in the front cost me to get replaced becasue I don't know how to set gears up? Are there major differences in years? The motors should be the same as well as the trannies? Give me your thoughts or suggestions? I am taking pics of both tomorrow as well as driving both.
