No doubt of anything else that's a problem is the T-tops leaking. Probably in any T-top car not just a G Body. It's tough not getting them to leak.

The Window Turbo offered by Pro Race Engineering fixed my slow window problem.
It's a quick n easy 5 min plug n play install
I did the Window Turbo in my 86' Regal it made a big difference

Electrical problems.

If you don't use contact cleaner on the fusebox at some point, you WILL be in a world of hurt.

Same goes for the gauges, my Pontiac had the traces destroyed and required me to solder directly to the terminals themselves.

Am I the only guy that’s had the leaver broke on the multifunction switch on the column for the turn single high beams wiper I think every other car I buy the damn thing snapped off and just spins and if it has cruise control makes installing the new one loads of fun

I haven't had that problem luckily, but I've seen countless amount of videos where people have had that issue sadly!

Wanting to take a sledge hammer to it, then find everyone at GM who made the decisions and seek revenge.

Rear “clip” in wheel cylinders. And the non standard flange on the ends of the 7.5 inch rear, with the two tiny M6 bolts. Why on earth did they do that - when a standardized backing plate with bolt in cylinder had been on the shelf - for what ? Fifteen years?? Remember them back in the late eighties/early nineties when living in New England. Already rotten to heck. Spinning and pivoting wheel cylinders. Recall buying at least one set of replacement backing plates from NAPA at that time.
