Slant 6 727 Transmission

it is all aluminum- no adapter to the block and bolted to the 203 like normal.
These 727's I have found in the wrecking yards on Dodge Vans often.But newer than 68 for sure.
A photo would be great. Maybe it was swapped into the truck at some time.
Rusty, My best guess is Industrial,but who knows ? I've said it before "Never say Never when it comes to Ma Mopar"
