What types of parts are necessary in order to rebuild the heater/defroster in a 1970. Seems to complicated for me to do so im going to give it to a mechanic who works cheap as a favor. The deal is i have to find the parts. Any advice

 

do you have AC or not? AC is a PITA, non AC is a 2 hour job with a friend BSing

There ya go, looks like the only thing they dont list for a 70 is the heater box assembly, but they have everything else: the core, blower motor, clamps and seal kits, control *****, and heater hoses. Im sure they will know where you can come across a box if you can't reuse the one in the car already. Good Luck.
