do the fender spears say 36 or 38? is the WB 123 or 135? there was a range of GVWs possible, and with the double [overload] spring pak in back it could be a heavy duty 3600 if 123" WB, but would be a 3800 if 135"
the under dash brake was standard on either a 3 or 4spd, but the floor mounted brake would only be on a 4spd, and that may have been an option on a 3600
