Technical Early chevy 3-speed synchronizers (SM 318)

Anyone know where to get'em? I bought a rebuild kit for $98...came with all the bearings, thrust washers, seals and gaskets - but no synchros. There's only two in it. I can't find listings for them anywhere.

Edit: Actually according to the ipb there's just one "synchronizer", but that assembly actually has a bronze synchro on either end of it that does come out.

 

Friend who used to work at a GM dealership in the 70s said they had a barrel full of those things, they sold a lot of them. It's one piece, the whole assembly, the brass rings are part of the large sleeve.

edit: they exist, just kind of hard to find and expensive.

Yeah - that thing actually has about 7 pieces to it, 2 of them being a traditional looking bronze synchronizer. I would think you could buy just those pieces.

The two grooves cut into the side of it here on either end are where you access an internal snap ring to allow removal of the actually synchronizers.

 

I think they pressed the bronze rings in, then machined them concentric with the rest of the part, making it into one assembly that must be replaced in it's entirety. Good design for making money for the parts department.

 

Squirrel is right, it is an assembly and they didn't service any pieces. I used to pull the bronze rings out from abusing the transmission (that's another story). I modified a pair of snap-ring pliers to let me pull the syncro blocks out and then tap the bronze rings back in and restake them. Then re-install the blocks. Almost like a new syncro.
