The ones that fit the early flywheels will work. Third Gen Automotive has them as well as others. They are set up to be safety wired to each other. The original 8BA ones have the large dimple in the center of the head and don't require safety wire.

If you use the ARP types make sure the bolts clear on the front side of the crank. The Ford & Chevy ones are 1-inch long. I'm not sure about the others. They generally have a relatively close shank fit in the bore. They can be shortened but it may be a pita if required for clearance. The OEM ones were short but I don't have one close by to measure.
