I have a very early production BW T10 4-speed fresh from a complete rebuild 4/23/21. Comes with a good used mainshaft and that "unicorn" bolt on yoke. All casting dates are within a week and the assembly date is G-27-2-2. No cracks, repairs or stripped threads. Ready for gear oil and installation. This is a 2.54 wide ratio. If you need this transmission, complete and ready to go, you know how scarce they are. Ships UPS from Mishawaka, In 46545 in a sturdy crate with insurance and usually runs between $120-180 depending on zip code. I believe $1,375 is more than a fair price for original rebuilt equipment. I can take specific pics on request.
