I set 4 threaded rod guides to raise and lower the body on, helped keep it straight and made the 10 up and downs easier..
4" hole saw centered the shift tower
Took a stock tunnel cover and traced on the floor to get a rough cutout section.
Shit tower wasn't dead center, but close enough to make a template.
Jigsaw took care of the transmission opening.
I removed the crossmember since I still don't have an acceptable transmission mount and used a floor jack to raise and lower the drivetrain through various angles.
Drivetrain clearance looks good now.. Might need to take just a hair more off toward the firewall..
Got the body to sit almost within stock guidelines... About 5/8 - 7/8"s off the frame...
