Hi,
The factory way and the way we done it at the dealership is out the top, raise the rear of the car up, so levels everything up and pull box and engine out as one.
The way I do it at home is underneath every time.
I have crane load leveller, that does what it says on the box, allows to adjust the angle of the engine.

As far as the bolts into the adaptor plate to attach to that engine, I think they are 5/16", been a few years since had a 4 cylinder hanging on mine, been V8's lately.
Cheers John
