Bob, I don't put a dollar value on my hobby/tinker time. How much is enjoying what you do worth to pay to not do it?
Question was on how to repair, not if folks thought it had a financial ROI, or if they would make the effort... I have the time and interest, and like fixing things instead of tossing them. IMHO every old part you toss is one less original to use.
Thanks Randy... I've got the disassembly part figured out and am pretty sure I can get them back together in working condition, just need to see if I can the right springs locally. I'll just leave the existing boots, as the heat sealed ends make removal very hard and it appears no repros are available. So they stay and just get cleaned up. If I get stuck or have questions I'll ping you.
