Fender's, wheel wheel's, rocker's, door's, tailgate, roof/windshield area.

Rockers, above the rear wheel openings, tail pan were the gate bolts to is the worst areas.

In I think 86 but may have been as late as 88 they started galvanizing and they are much less prone to rusting out. Before that they don't even have paint on the insides of the rockers and that;s why they rust out so bad. Same problem that the 67-72's had rotting out up around the top. No paint and it would form condinsation.

My 82 Jimmy had a leak that was in the seal between the fixed roof and the removable roof. Unknown to me it had been leaking for years, basically ruining the floorpan, front and rear. Check out the floorpans on any vehicle you are interested in. The repair of these is a bear (or at least it is to me.) There was also a small leak around the front windshield, Someone else mentioned a cowl leak. Good luck.
