Very interesting. You may have saved me some serious grief. For the good of all mankind, I was all set to quarantine myself in my garage today to finally assemble my transmission and then I stumbled onto this chain. Now I'm considering re-using my vintage roller bearings I had planned to...
I just tried that number (303-483-3896) and reached a guy in Denver who assures me that he is not John Holland and he knows nothing about rebuilding Model A shocks. I'm pretty sure the correct number for John Holland is 330-483-3896.
