M-code A-body question

I’ve got a 65 426 Street Wedge block from out of a C-body that has them drilled and tapped. I guess that’s because the big block C-bodies of that era used that same mount. I also have a 64 426 Street Wedge block from a B-body that has the bosses but they are not drilled and tapped.

I think it’s only the 65 C body that uses that same mount. I was asked by a friend to check my honey hole for a 65 C body for that bracket, and it was on there. Didn’t grab it yet, it’s pretty buried in the dirt, can’t even get a Jack under the car.
