You can wait until the engine is in the car?

Spacers & longer bolts when you hang it on the stand.

That's the only other way I could have seen it done. Too late for that though. You NEED an engine hoist.

The oil pan seals to the adapter, so it has to be installed before the pan.

... to clarify if needed, just the adapter plate for the seal has to go on before the pan. Not the actual seal.

That's what I said...the adapter. Should have been clear.

I thought the "it" in your sentence was an understood reference to mean the seal. A thousand pardons...

Just as an option....but you need 3 people....2 hold it while the 3rd loosens the bolts then lower the block so you can get to the adapter without too much struggle and tighten the bolts (u can also flip the motor and raise it with manpower)...it'll still be tight but it canbe done...definitely go buy a picker though, harbor frieght is cheap enough...

Harbor Freight is cheap but you get what you pay for. I got my hoist there and if I would lift the engine 3" off the floor, within 10 minutes it was sitting on the oil pan. They work for the occasional engine pull/install.

I did it on the stand using washers as spacers with longer bolts.

I was just about to post the same thing! Spin the engine upside down and you should have plenty of room, Just like shown in the pic above.

Why not wait until the engine is in the bay or just prior to putting the flywheel/flexplate on?

The adapter, yes. Not the actual seal.
