CAN'T FIND 1970 DART 340 HEATER CORE AND EVAPORATOR
If you have the two reconditioning kits for the A/c and heater , they are pretty straight forward to recondition. The vacuum pods do have the lines on correctly, they just don't function properly if crossed, just switch. It can be fun getting the units into place, the heater assembly goes in first. The kits are available, but I think Detroit Muscle makes them. Will look to see if I kept pictures of my '72.
