12A Rotor Housings

What is the difference between '79-'80 and '81-'83 rotor housings? They have different part numbers.

Thanks,

I'm not positive but I think it is the number of bolts that run through the housings and irons and hold the whole engine together. There are probably a couple other differences too.

That, and the SA housings are NOT interchangeable front-to-back, the FB housings are.
