I've been bugging you fine gentlemen on other threads for specific issues and I appreciate the help with getting the mounting location sorted out. I discovered that a light trimming of the trans tunnel top lip allowed me to hit 3 degrees, clear the vette rack, and get the engine tucked in close and low.
I left some of the recessed lip and mounting hole so I can easily attach the trans tunnel cover once modified, and I'll clean that up with a grinder once the engine is out again. It only needed some of the unseen sheet metal trimmed, which I'm very happy about.
