Starter mounting bolt holes are OK. Plan to use high-torque ministarter.
Starter Pilot broken on my 1967 727 transmission case.: Is case useable?

Bell housing before clean up. Starter mounting bolts look OK.

So its not really needed - there are starters sold that do not use this pilot hole. I like to use it. It is repairable, but is it worth it? I have the capability to fix that in my shop. But if it were mine, I would replace it. But I also have several spare cases.
 
Like said above the outer half is intact and that will locate it. The starter has a wide flange and two 7/16" bolts holding it down.

I would run it!

Too many rear wheel drive GM products in your space?
LoL no, those are OLD bad memories. I have only one GM product these days.... a '16 dump truck that I bought brand new. Not ironic i guess, the starter failed when the truck was about 8 months old. /rolls eyes
 
Post#2 Requested a test fit. Looks good to me. I don't think the gap between rear of starter and bell housing will make a difference.

You will be FINE. As I said earlier, the force when cranking is trying to push the boss outwards, & the boss is ok in that area.
