WOW!
That has got to be the easiest install I've ever done.
OK, I've only done less than 20, so maybe I don't have a broad range of experience.
I was having trouble getting the pins to align with the bell housing. I took a break, and went in to recruit my son to help, (he's 6'4" and could probably bench press the block) when we came out to work on it, the hoist had settled a bit, and the pins were all in place!

Or maybe it was the little people............
