Accessory drive for gen 1 small block 350 to keep factory ac in a tbi truck

[Mitch4x4]

Got a quick question for you guys, Im going to be swapping a 350 into my 90 chevy k1500 from a 79 camaro and i was wondering what you guys have done to keep the factory a/c on these tbi trucks. Being that the head on the passenger side has only one hole to mount the factory ac bracket.

Appreciate any feed back from what you guys have done.
