Hello, I just put a alpha 1 gen 1 drive in place of the original mc1 drive which had 6 holes in the gasket, now the alpha 1 drive shows I need the 7 hole gasket.
What is the 7th hole for? is the original 1977 mc1 gimble o.k. with no cavity matching the 7th hole can I use the 6 hole gasket?

My guess is that you are looking at the hole for the oil reservoir check valve on the Alpha I gen II outdrive. It's not needed on your drive, and won't hurt anything.

Forget about that hole in the drive, it means nothing, it's a blank hole. Probably for casting and machining. Use the gasket for the 77 and you will be fine.
If that is the drive you are going to put on, I would guess by looking that it needs new ujoints, and probably a new yoke, and input shaft seal. It's all rusty, probably from water in the bellows on the boat it came off of.
