If the bore cleans up well with a hone you could rebuild it with a kit. NOS rebuild kits are pricey but aftermarket kits usually run about $30 if you can find them. If it needs a sleeve then I'd find an original Bendix casting because that runs more than $100. Somewhere in my files I have part #s for various obsolete rebuild kits & MCs if you want. Also think I have an old aftermarket USA casting you can have for shipping cost if you're interested- it failed due to a scratch in the bore & would need honed. Easiest route would be to buy whatever aftermarket replacement you can find & cross your fingers that it works.John, Thank-you. There shouldn't be any reason NOT to have this unit rebuilt? correct?
Looking good! Those pipes forward of the mufflers are originals, the underbody looks solid!
That's an old aftermarket unit Mike. Dead giveaway is the rounded rear, originals Bendix M/C's were squared off at rear & rounded in front. The lids don't interchange. Like most stuff the older aftermarket were made in USA & newer in China, some can be of suspect quality.
I had my original sleeved with no issues. There's a couple of good places that do that. Rebuild kits can be hard to find, I've hoarded some when they pop up.
Here's a few pics of the originals-
