Greetings and welcome from across the river!

To check the flex disc, you can inspect it pretty well by removing the starter; I just got one with a shredded disc, and that was the easiest way to check it. There may also be some ability to see it by removing an access cover on the bellhousing, but either will require getting under the car.

I would expect the engines could be interchanged, but not 100% sure - perhaps someone else out there could confirm.

I'm not sure I'd want to tow an auto with a tow dolly, not sure you'd get adequate lubrication, but that could be OK for a short distance/low speeds (like across town).
