C3 Differential mounting
Here is my question to all of u. The crossmember that the differential is bolted to (4 bolts) has rubber mount bushings on the ends. After removing the two bolts that hold it to the frame, it is really difficult to get the crossmember to release from the frame. I used two pry bars on either side to get it to release ( it did with a pop). Any tips for how to lube those mounting points so future removal won’t be so hard? I have swapped rear drive ratios at least three times so looking to make the job easier.

Anyway you want to get rid of the rubber mounting. I air chiseled and ground away the tabs to make the rearend solid mounted and differential raised using the crossmember end bolt and aluminum disk kits.
My exhaust is a one piece because of my cross over "H" pipe. So, I unbolt at the headers and then just two hanger points on each side to remove the exhaust. I just lean it up against the wall to do any power train work. Oh, I made the tranny crossmember to be an exhaust pass under to make it all less complicated. You can just buy those type of cross members
