Blazer quarter panels.

[kanuck]

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.....

They should be all the same from '81 to '91
The door are the same as on a pickup.
