I have a 1950 B-2-B flathead 6 and 3 speed trans available in Denver, Colorado. I had the engine running ~5 years ago, but I don't know about the trans as the truck's brakes never worked. It is on a pallet and can be set in your truck or on your trailer. Probably not worth shipping, you need to be local or willing to drive.
This is not a classified ad, as I intend to give these parts away for free. It would be nice if the the recipient could buy me a nice bottle or maybe a case of beer, this isn't mandatory.
This will go to the metal recycler's if nobody wants it.
