I am finishing up my heater box resto, How many screws hold the heater core and condenser in place and where? My box has been out out of my Challenger and apart for a few years now so those screws have wondered off. I am pretty much done except for mounting the condenser and heater core and screwing the two halves together.

17 holds the two halves of the box together. 4 each for the evap and heater core, if I remember right. They are near each corner. Trial fit first and then drill holes through the new cores if needed. When I replaced mine, I dry fit them in and drilled for the bolt holes because the cores didn't have them done. BTW- On the halves for the heater box, I have exact original bolts, new, if need some, P.M. me
