Can you weld? If so look at 98-02 f body mounts and possible newer camaro, and it's been a while since i've seen tbss engine mounts. All of these mounts sit low, completely out of the way of everything. If you mocked these up i believe a welded on perch from your stock crossmember rearward would have a clean install. The cpp mounts look like they come up and on top of your frame, in the way of headers and A/C. I used the organ donor 5.3 in my 68 and i will be doing stock A/C down low on the ps side. I made my own perches down low on my crossmember using 2001 4x4 mounts because it was there and and i knew there would be no mounting hassles using gm stuff. Nothing against what most are doing, i sometimes go out of the norm. Good luck, Brian F.
