Has anyone successfully used the USCartool A500 Crossmember?

Working like crazy today to try to get this finished up and ready for test drive.
Just stopped for a quick lunch, then back out to the garage.
Still need to do:
Install starter
Run wires from trans to console for o/d switch
Install cooler lines
Install dipstick tube
Start filling with ATF+4
Reinstall front section of exhaust
Maybe fire it up, still on the stands, and just run through the gears and make sure it shifts right.

Maybe tomorrow get it back on the ground and take it out for test drive.
