Help ID this set of pedals if they are from Slant, 318 or HD style like 340 and BB darts

I know the B/E body ones have two versions. One with a plastic nyliner bushing and another that uses a pair of cage bearings. I'm not sure if A body had the bearings or not.
If you run a diaphragm style pressure plate it shouldn't be an issue which style you use. You also wouldn't need the the over center spring.
