A Ford 9″ Rear End seems to be the go to suggestion for G-Body enthusiasts. This is the case because of increased power handling, hypoid offset, additional pinion support, efficient gear swapping, and aftermarket support and costs compared to a GM 8.5″ rear or building a 7.5″ (especially when you’re paying a shop to do it).
Here is a list of Ford 9″ sources for G-Bodies:
