All...original.........gear......drive.......starters.........bolt to any engine they were ever used on, so all slants, all small blocks, all B/ RB and I'm even told they can be used on 426 hemis, though hemis did not come that way.
Only issue I have heard of with "minis" is that some have an adapter "thingie" on the electrical terminals which might need to be removed. Some V8 guys had "clocking" issues with B/ RB I think but some starters can be "clocked."
