missing bolts

[Leadbut]

I just installed my 390 back into my '69 amx. Everything lined up nicely. When I went to bolt the bell housing (t-10) to the block I couldn't find a single bolt. Looked everywhere. Wife just told me that she threw them away. (She thought I was finished with them!?!?).
Well at least I'm not nuts.

Anybody know what sizes and lengths?
3/8, 7/16 ?

Thanks

check the holes in the block I think they are 3/8 on the bellhousing with the outer two possibly being larger. just find a tap that will fit the hole properly and measure the thickness of the bellhousing and add the depth of the hole to it
