3 FISH LIMIT AL's BUDGET BUILD

Got My engine fired up today , finally. The first distributor , one of those Chineseium kind with the GM module in it. It would fire but not run. pulled it out stuck an old stock points dizzy in and nodda. Dug up some old points that I took out of the van ,put in the dizzy and fired right up. Sounds good, couldn't run to long without any radiator. Starter sounds like **** . It keeps dis engaging and eating the teeth on the flywheel.
Question # 1
It's a 130 tooth fly wheel . Is that the same as a torque converter ring gear ? They don't take different starters do they ?
Anyway I just ordered a new mini like I should have in the 1st place. Hope they're the same. And I have a new :realcrazy:chineseium dizzy coming to.
My new Champion 3 row radiator showed up late to day, got it mocked up in there . Looks like it will work out nice.
Having issues with the throw out bearing. It keeps coming loose off the fork. Only thing I can figure is it's not the right one.:rolleyes:. It has a plastic collar that slides on the tranny snout instead of cast iron like the good old ones .
Question # 2
Anyone know the part # for the right one ? Cast iron.
