A couple of things to clarify...
Not a stock disk. Got it from the guy in TX and it's thicker at the center where the spline "core" sticks out on one side and the spring plate extends on the other.
I apparently need to do more pushups, because there was no way I could hold the pressure plate with one hand, get it in just the right position, and then start bolts with the other hand.
And lifting the engine 6" made it easier to slide the plate and disk under the bell housing.
A second pair of hands had it done in 10 minutes. I held it in place (with two hands) while my friend started two bolts. Then we rotated and inserted the rest.
May have been a chicken wing way to get it done, but it got it done. And that's what counts.
