5.3 to th400

I just want to be clear in the order I need to put things so this install goes off without a hitch. I have the torque converter snout spacer, the crankshaft spacer, and the aftermarket dished flexplate. The reason I'm asking is that I've seen installs where all that was needed was the snout spacer and flexplate, and others where the crank spacer had to be there too. Ill be doing this alone, so I'd really rather not put the motor in set up wrong and have to pull it back out.

I used just the snout spacer and the dished flex plate. No problems. No need for crank spacer
