the crank spacer is right behind the harmonic damper, if it's external it will have a hatchet weight behind the damper that you should be able to at least feel. Also you can look at the block right above the starter, if it has D9TE it's a 79 or later model and should be external balanced.
As to the flywheel/flex plate question, no you can't use one from an early 70s model, it has to be for a 79 or later model engine.

thanks for all the information. I was looking at the motor last night yea it does have a hatchet weight behind the harmonic balancer so it is externally balanced. I will look for that number marking above the starter and get back to you.

yep but youll probably need a 1/4 or 3/8" spacer plate between the bellhousing and the block because the flywheel is a little thicker and the clutch kit is a little thicker

I have done 4 swaps using the 400 bellhousing and have never used a spacer. If your buying a flywheel get one that has the bolt pattern for a diaphram style pressure plate.
If you use a spacer be carefull not to pull the pilot shaft back too far out of the pilot shaft bushing.

460 swap
I've done 1 460 swap before but that was on a 78 that had a 351M before and we didn't need a spacer. does the diaphragm clutch have a different style bolt pattern then the 3 finger clutch?
