CHARLIE - Glad You mentioned that about TC.com. I've never done business with them, just browsed their website after seeing it mentioned elsewhere. Guess if I need anything it'll come from Gempler's or other GOOD suppliers!
KENDELL - First set of chains I ever had for the 72 was a pair of emergency chains for a small car like a VW Rabbit or Ford Fiesta (Dad had a '78 Fiesta for a couple yrs & 100,000+ miles, Great little car!) The chains had woven nylon side straps and plastic crossbars with a couple tungsten studs molded in. They worked but were short-lived. At least the plastic was yellow so they matched the CC.
Like most other things I imagine chains are made in China now, and with their dismal metallurgy I doubt new chains last as long as 40 yr old chains.
