Aluminum case Duplex hand brake mechanism

[SuperB]

I'm looking for a hand brake mechanism and mounting bracket for a 1965 B model Duplex transmission. It might have to be from an aluminum case transmission though (TRDL-722).

I have a brake mech from an earlier cast iron case transmission (TRD-72), and it has a different mounting arrangement, so it does not fit on the aluminum transmission for my truck.

The one I need looks like it mounts using 2 studs that are right next to the main shifter attaching bolts, and also uses 2 horizontal bolts that go into the side of the transmission cover down near the gasket surface. I'm guessing at this, because I can't find a diagram for my transmission. I can try to post a picture if my description isn't clear.  

Please message me if you might be able to help.  Thanks

not to be a bearer of bad news, more to let you know your post is being read : BUT there was a duplex 10 speed / alum rear half at the farm in CT I help out at. went looking for it yesterday for numbers etc== it's gone ' they buried it when fill was brought in or it went to scrap yard with other stuff. the rear end from the Mack still there .

Not sure what the end game here is but if you are looking for one to have a functional parking / emergency brake most guys abandon the hand brake and convert the brake chambers to spring chambers. If you need to have it for an exact nut/bolt restoration then that is a different story. Probably be hard to find or may have to buy a whole parts truck to get what you need. Do you have any photos of the one you need?
