Transmission adapter to mate a slant six to a smallbock trans

These adapters were installed on 64-67 Dodge A100 and A108 trucks and vans, as well as in taxis, cop cars, and other fleet vehicles that used a slant six. I need the adapter as well as the crank spacer.

I need it to be fairly close to the Puget Sound area since shipping will be expensive. THe cheaper the better, the closer to Tacoma, WA the better. Any leads appreciated.
