Yep, just what Jerry described. Pretty cool someone is going this.
I remember when in the 80's the dealers ran out of automatic shift cables for a 68 GTO. Everyone was burning them up by not replacing the engine ground strap .. turn on your headlights and it would heat up the nylon liner and ruin the cable as the engine grounded through the shift cable.
About two years ago I ordered a brand new GM crank damper for my 68 ... did a search on the part number and it turned up some dealer had some.
