[6BT 56]

That's a cool truck. Sure looks like napco stuff. I hate to see that kind of stuff get taken apart but really it's pointless to build a truck unless you can enjoy driving it . My 56 had all napco parts under it and it was no fun to drive at all. I now have a D60 D 70 combo under mine with the cummins and its like nite and day . Runs good. Stops good power steering and actually is good on fuel as well. Also can get pars anywhere now . I sold my napco front and rear, the trans and the t/c for $ 2500. Keep I mind the only rare parts were the front doff and the t/c. The rest was the normal stock stuff. I like where your,going here will be following along for sure .
