Mounts for LSA in first gen Camaro

[billohio]

I am getting some parts around to put a LSA in a first gen camaro. I have read the post where my stock frame will need to be notched for the a.c. compressor. I wondered if anyone here that has done this swap, what did you use for motor mounts? Do the Holley mounts move the engine back into the crossmember more? Are there any lower compressor mounts that help with the frame notch? I will be adding vintage air and they sell a bracket but didnt know if that was the one I need.
I will be using a TR6060 transmission and sounds like I need to make my own transmission crossmember.
Thanks in advance and I appreciate all the posts with good info here!
