I cannot seem to find this part number for which manual box it matches to.
Trying to gather parts (new) for an 89 box rebuilt.... Slowly.
The fact that the rebuilt parts are adding up a respectable car payment on monthly terms is telling.

That part doesn't exist in PET- what is it supposed to be?

Huh. That doesn't look anything like the 85-95 928 tranny B-W synchros, or any other picture of a Porsche synchro I can find.
I'd venture that perhaps userid863753 has made a clerical error in their Ebay auction.

That Part number does not exist in the Porsche system. As Rob said.

Those are the engaging teeth that fit onto a gear, for a 911 G-50.
Porsche never offered those as a separate part if they got damaged (you had to buy the entire gear set) but some of the savvy aftermarket suppliers went to the gear makers and were able to obtain these teeth. They "assigned" a part number to these teeth that made some sense.
The following pertains to the engaging gear teeth in the picture and to the 928 variant:
The teeth are installed onto the gear and then the internal teeth are "swaged" by a machine to keep them on the gears. They can be removed from the gear (very difficult, without damaging the actual gear) and the "smashed" internal teeth can be machined down, so that new teeth can be installed. This is a critical operation, as it is easy to distort the inner bearing race when the teeth are installed.....which ruins the actual gear. The difficult part is how to retain the "new teeth"....since the original material to retain them is no longer present. ("Replaced" teeth tend to "walk" off of the gears and jamb up the synchros.)
Proceed with caution, when considering changing "engaging teeth" on both the early and late 928 transmissions. There's an entire "subset" of knowledge required to be able to install and retain the replacement teeth!
