Looking for a 7.5" lsd for a 83-87 starion.  Hit me up

So I have been thinking of running rear non SHP wheels on the front without having to roll fenders,  limit steering, and reduce scrub. Some say they have done this with no issues and others with the same size tire say it rubs everywhere. I can only think of 2 simple methods and one is machine the back of the wheel, probably .200 max off mounting hub. The other would be a hub off a different car that has the flange more towards the strut. For example the 1987 300zx turbo uses the same bearings in

Probably won't be economical, but this would be a cool motor swap if they release it    https://www.autoblog.com/2022/12/20/blueprint-engines-performance-racing-inndustry-show/

I started a brake change yesterday and got one side of the rear done nice, but when I got to the second side the piston was juuust out enough that I couldn't fit the new pads in. I tried compressing the piston with a standard tool but it didn't want to go in at all and knowing how hard finding some common parts are I wasn't about to embark on a caliper rebuild the day before I needed to get to work Is there anything specific about our brake systems that needs to be done to allow the piston
