BIG PROBLEM! I just counted the teeth on the flywheel, 152, which doesn't line up with ANY known flywheel, 427, 428, 429. I called Gessford Machine (those sure are some nice folks by the way) they confirmed it's an odd ball. The size is correct, 15.5" inches. Anyway, I ordered a 184 tooth all ready so I got my fingers crossed it will fit.
It's likely I've had the wrong ring gear all this time and THAT may account for the numerous starter problems I've had over the years?
I'm moving later next month, this is the worst possible time to be dealing with flywheel issues and a car that won't go.
