rear brake upgrade

[L92 OLDS]

I've done this swap on my 8.5 using the 2wd Blazer set-up. The caliper will hit the frame. The frame will need to be notched. Haven't installed rear into car yet. I did consider the LS1 rear brake swap but didn't like how the parking brake was set up.

Thanks for confirming. The second picture clearly shows how the back the caliper will interfere with the bump stop.
