The flywheel for 60-66 305 V6 is a 191 tooth. Don't see any 6.2 with that tooth count. I wrote to RockAuto trying to get them to understand that the reason they have had no negative feedback is because the F/W they list does fit a bunch of newer Chevy's. I asked then to see if any were ordered for 1965 series 1000 GMC V6. The ring gear they offer does have 191 teeth (out of stock). The flywheel they have (167654) is a 168T I think, go figure.
Buying parts for these is real tricky sometimes because nobody knows what they are doing or selling. The 305 V6 is always confused with other V6's and the 305 V8. (5.0 fools them). We all have to be careful and compare the old part when possible. I am realizing, as is probably Champagne, that this ain't going to be easy to find new. I have searched for a long time and not found anything actually available except used on Ebay.
