Run Stand Bellhousing

So my dad talked me into building a run-stand for my 318 before putting it in the car. I have a 904 from John Cope but we've decided it would be a lot simpler to just throw on a bellhousing and flywheel for the stand.

I've seen truck 318 bellhousings on eBay for half the price of A body ones but I'm not sure if this will cause issues. Anyone have experience with this?

The only info on the bellhousing I'm current considering is:

#2899163 4spd 318 360 1969-1971 Truck

Ideally I'd like to find something that will let him use the flywheel in his D150 but I think he has an 11' clutch. As I'm sure you can tell, I know little about manual setups so please educate this noob.
