I added more to that list I just wrote. Go back and check it out
Most everything you added I've accounted for. Chev isolator etc. I have an HGM controller for the shifting and lockup, pretty sweet unit, ain't cheap, but it does integrate with the Sniper system. the PATC I'm not a huge fan of, we put one on my Son's Ramcharger and it works, but in the mountains it's sort of buggy.
The car is a column shift big block car, so I cut off the bellhousing and put an ultrabell on it for the BB bolt pattern. Unfortunately the ultrabell doesn't have the shift linkage mount on it so I cut off the old one and had it welded onto the new bell.
The cooler lines, huge thanks for that as I was scratching my head on what I was going to to there, I really didn't want to bend up my own lines from scratch, I have OCD and I would've been pissed at myself the entire time.
