After determining that the gears were better on the differential that I bought at the swap meet, I needed to get the bearings off the carrier as they were shot. I tried soaking and pressure from a puller for a month but they were stuck.
Finally I decided to destroy the bearings and grind the inner race off the carrier, so the first three pics show that. It seems that whoever took the last set of bearings off the donor differential, did so with a cold chisel instead of a puller and left some big burrs on the carrier. Anyway got them off, cleaned up the burrs, and pressed on new ones.
Next is a pic of the spyder gear in its housing and the top half of the housing. You can see the date stamp of 4 29 31 in the housing so this differential is 3 months newer than the roadster.
I had to remove the old spring shackle bushings from the rear spring and differential housings and they were very stuck. So I turned a bushing driver in the lathe and was able to drive them out of the springs with it but the ones in the housings were still frozen in place.
You can see the driver in the spring eye on the anvil and in the housing in the next picture.
