The rubber boot at the top end of my intermediate steering shaft is cracked. I also wonder how good the rag joint at the bottom is after 33 yrs. Can you buy replacements? I haven't seen any. I looked at the junk yard and it looks like they are pretty much the same in a lot of GM cars around that time so I can easily find a used one. By I don't want to replace 33 yr old rubber with 30 yr old rubber. So, what's the deal with these things?
