So far so good
You da Man, you ripped through that rebuild, install to running, good job, this so reminds me of when I was doing my engine rebuild & many clutch changes on jack stands on my 97 Cobra. It can get grueling. Nice Trans. jack, I had the same Trans. scissor jack. Works great.
The 2x4 on the floor jack is the way I do it also to put the exhaust back up, but like
@Speedy! said, to take it down, I just drop it on my chest & push it out / off.
I know your Happy to be done, Congrats !!
