The foot starter engaged the gears and activated the starter through a switch mounted on top of it.
If you want to retain the flavor of the foot start, you could probably wire a switch (maybe a brake light switch) between the 'run' side of the key switch and the solenoid. Or, even straight from the battery, if you want to be able to bump the engine at tune-up time. Mount the switch on the bell housing so the original cross bar from the foot starter will activate it.

Just re-read your question. I don't think the teeth are the same. That's one reason that those who change to a T5 trans have to find the right clutch disc, so they can keep their original flywheel and foot starter. If you have the flywheel off your old engine, you might be able to swap it to the new one.

Good luck.
