Hi willowgrass, I doubt anyone would rebuild a D8 engine and not use it. Probably the D8 engine/block for rebuild could be found - they must be out there. Then, the shipping cost could be prohibitive. You should be able to find a working trans that doesn't need a rebuild. '38 Ply, Dod, DeS and Chr6 should interchange. Also I think the cheap '39 Ply had floor shift. '37 Dod (and other Mopars?) had floor mounted parking brake.....it could be a different setup that doesn't work with your pistol grip parking brake. Where in China are you? Tom
