If you truly wanted a solid mounted differential, the proper way to do it would be to replace all 3 of the original mounts with solid bushings. This would keep the stresses spread out rather than focused at one bracket at one corner of the differential.

Thanks both of you, I will take your advice!
I don't have a garage otherwise I would not hesitate to replace the bushing myself. But right now, the best I have is a parking lot with no access to 120v power. I was thinking of buying a cordless sawzall and cutting the old bushing out, that seems easier than using the bushing tool from Z1.
Also every shop I called does not have experience replacing this bushing, but said they can do it and it will cost a lot. I wish I could find a shop that was familiar with Zs and knew about the bushing issue and replaced them before.
As a guy who has done motor swaps and head swaps and lots of other stuff, how much of a pain in the "A" would it be for me to replace the bushing myself with hand tools? I don't want to get stuck somewhere in the process and not be able to finish the job.
