Default Right Part Numbers for GM Manifolds?

Trying to figure out which would be the right manifolds for an A/C retaining single turbo setup using the C6 passenger and truck passenger manifold.

C6 looks like a 12603760. I'm pretty certain of that.


And truck it looks like either 12567484 or 12600527 (which seems to have replaced the 484).


Would those work? I'd like to buy new if I can. Thanks.

Guess not? I'll order and see. Not a big gamble, I guess.

I used a C6 LS3 driver manifold on the passenger side. It's tight, but it fits around the AC compressor.

C6 Passenger will work well, Huron's passenger manifold is modeled after that one.

You're right. I hadn't noticed that.

The idea is to create a 2.25" crossover merged to a T6 flange, run a pair of 38mm wastegates, and relocate the alternator using the CBR bracket while retaining A/C.
