Thought I would share a tip
In the past I have done engine swaps out through the hood (I can't tell you how many, LOTS!) and this time I decided to go out from the bottom. WOW what a switch. This was way easier. I fabricated this dolly to rest the engine and transmission on.
I welded this up with a couple "pins" sticking up that slide into the small holes in the K-Frame, and a small "V" that supports the trans.
The next step is to simply unbolt the upper control arms, four bolts holding the k-frame to the car, disconnect the exhaust (this is easier at the collector rather than the headers), slip out the drive shaft, and pick up the body. Roll everything out from under the car then do the dis-assembly.
Here is the dolly under the car:
Picking up the body, soft straps keep from doing ant damage:
