To understand what's going on you need to understand how all volume OEM parts, and not just volume car parts are manufactured. I have no doubt that your original starter was manufactured by Bosch or one of their qualified subs, which allowed that sub to use the Bosch name. But once a part is no longer used for production, the license to build that part and often the assembly line that manufactured that part are sold to a smaller second or third tier manufacturer. The reason is simple - current manufacturing space has to be converted over to build what's supporting today's models. It's likely your starter was rebuilt by Bosch, and it's just as likely that the parts used were not manufactured by Bosch but were purchased by the rebuilder from one of these second or third tier manufacturers. The parts being built today to support starters that were manufactured in the 80's are supposed to be manufactured to the same specs as the original parts. Sometimes they are and sometimes they aren't. The problem is these manufacturers are building to a set of 'specs' and not to a strict design.
Thanks, Tom Hargrave

Having had bad experience with some aftermarket SR28X starters, I bought a "Bosch Premium" branded rebuild.
My old starters have Bosch markings stamped in the black metal motor housing. (Both the very old large type that came with the 82, 83, and the later smaller, permanent magnet gear reduction starters) The rebuild I just bought has no Bosch markings. What have others found on their rebuilt starters?
Do rebuilders generally reject non-Bosch parts, or reuse any cores they get?
I would mostly concerned with the copper windings in the rotor of the PM motor. That's what has been bad on the aftermarket starters I tried.
