Update: Thanks for all the help!
FYI a new non-counter weighted flywheel for these cars between 62-68 is hard to find. They were even used on the V8's 283 and 327's but at least here in tx the local shops can not get you one. GM had one actually for $300.. steep for me!
I went digging through many junk yards and found a 10" one...had it turned (saw another 9 1/4" recessed one too! They did exist!). Got a complete 10" clutch kit. Changing everything out this weekend. Gona be real happy or real %^&&*#$%%&*.

Let you know, Clyde
