I assumed they were the same .625" as previous SBC, but the GMPP part lists .621". I don't want to get 5/8" dowels and have them be too tight, but also don't want to get .621" and have it be loose. The only pins I have are so wasted and rusty that I can't really measure them. Only thing I have to measure the hole is a questionable set of chinese calipers that I trust about as far as I trust a politician.

Can someone help me out with the correct size?

.621 is the correct diameter for the bell housing dowl pins.
