Given the OP's address, the reality is, he may be better off locating a complete truck to get the good used parts he needs, especially if he needs a lot of stuff. He should be able to at least find good sheet metal in his area. The good used stuff will fit better then the new aftermarket stuff will, in most cases.
Once the truck is in his possession, the individual parts he needs can probably be sourced. As he has already found out, these old Dodge parts are not easy to find these days.
Yesterday on FB somebody from Cali or that general area posted up a rust free tin grill cab for FREE because he bought a parts truck and took what he needed. In this part of the world a cab with less rust than the one ya got is an easy $500, apparently they can't give em away out there.
