A get well wish. I put a new (reman) rack in mine about 4 years ago. ZF unit. Driven by the Saginaw pump on my LS power plant -- the steering has never felt better.

My mom suffered from disc issues for decades. One of the things I learned is that while the steroid injections helped give her relief, in the long run they contributed to bone loss in the vertebra which ultimately exacerbated her nerve/pain problems. Because of the bone loss, surgery to brace or fuse the vertebra was not possible. Near the end (last 1.5 years) her only option was massive opioid doses. So -- if you haven't, talk to your medical team about the long term implications of steroid use in your case. And another, closing, get well wish.
