Are there any rear oem disc brake swaps available?

[V6UnderPressure]

We all know about the B-Body 12" front brake swap. But what about the rear? Are there any disc brake setups from another GM that will bolt up to the GN? Just curious as I do not attempt to do anything like this anytime soon, if ever.

nope- nothing that will bolt right on.
GM never engineered a mounting bracket for any of the vehicles with the f'ed up axle flange that they used in the G bodies, F bodies, and S trucks. all the F bodies that got rear discs used the 9 bolt rear end, which had a 4 bolt axle flange that used a different pattern than any other GM car sold in North America.
