I have never researched them or put enough thought into this to give any pointers. Back when, it meant giving up your parking brake and also required installing a proportioning valve (plus some panic stops) just to get performance back to stock levels, that was enough to sour me on the idea. I did a quick search and found a Car Craft article that said 90's F-body rear disc set ups fit pretty much all the earlier GM 10 and 12-bolt axles but it didn't specify how trucks fit in. What kit are you looking at?
