Any progress?

Sorry to leave everyone hanging but I have been on a 5 day raft trip shooting the rapids in the bottom of the Grand Canyon. No internet , phones, or electricity. AWESOME trip!
Anyway back in the Hotel in Vegas.
Pulled transmission and took it into the shop the last day I was in town. Really have no idea where to go now. Pulled the 513 bell and there were dowels in place. So

Starter stock and matches other original starter. Flywheel, 130 tooth, 13 1/4 diameter. Bell housing, 513, alum. What the #$%!.

Guess I am going to replace the bell since the two bottom trans mounting holes were stripped and I had to heli coil it. Then going to try to borrow from someone in the club another flywheel and test fit it with the starter. Not sure what else to do?

Tip of tooth to tip of tooth

Mike I have a Mcleod billet 6 bolt steel wheel , it measures roughly 13 5/16 across the teeth. I have yet to install it on anything so I can only ASSuME it's correct.

Final results:
Club member has 70 dodge super bee 383 car with 4 speed. All original parts. Took flywheel, bell housing and starter to his house.
Flywheel exact match.
Bell housing - exact match, even the same date code.
Starter - exact match
So what gives???????
Dowel pins. Both looked like off sets. Pulled them, put in stock straight ones.
Got out the dial indicator. It is well within tolerance. Bolted up the flywheel and put the bell on. Starter fits!
BUT! there isn't an imput shaft bushing in the crank!
Ordered one.
Transmission was "rebuilt" BUT none of the seals were replaced. So had it completely gone through by a local Mopar knowledgable shop.
So thanks to all who helped on this thread and special thanks to Wayne Brewer.
