Technical 350 turbo 153 tooth flexplate question

I have a 153 side by side starter - just trying to tap the infinite wisdom of the Hamb and save the few strands of hair...
Thanks for pointing me the right direction

 

pic of converter looks correct , when converter is slid all the way back to the pump typically 1/8 to 1/4 gap .....

A """153 tooth""" flexplate / flywheel use the straight across
( holes on same side )
((168 are diagonal)))

Metric bolts with a
""" Oem production Mini style starter """
use the metric ""Headed Bolt Head)
The head is Mitric
The threads are 3/8 -16 ,

"" NOT """after market mini starter ))

"""Standard """ Big motor starters use
SAE headed bolt head with 3/8-16 threads

The Starter NEEDS to match Flex plate
Bolts need to match starter USED
No matter what transmission Used !!
