70 D100

I forgot to mention I replaced it with another one. Exact same casting number.

They can be found relatively easy because most people V8 swap these trucks.

Yep. Finding it cracked was a complete surprise. I had a coupe of days to get the clutch changed and had to braze it up quick. Still holding up after a year. I’m still working out plans to fabricate some kind of strut, 3/16” steel, fitted between the starter and the bell. I’ll bolt the flywheel to the mock up engine and check starter gear engagement.
Really great to see you got this one going again with the original drivetrain.
