I just recently got an 1988 4wd blazer which has a fair amount of rust in the back quarters around the wheel wells. I was talking to a friend and he lined me up with someone who has a pair of quarters that were bought new a few years back and says they are for 1982 to 1986 blazer. Is there any difference all the way up to 1991 in the body parts? I know grilles changed several times and some rad supports are a bit different for head lights, but is there anything else? Do all tail gates and doors interchange? Are the doors different then the pickup trucks?
Thanks for any info.....
