Will 76 heater controls fit a 78?

Since I never brake & change the heater at the same time, it probably won't make a difference if I removethe vacuum bottle.

Yes, I had an a/c shop removethe pump. I still have the evaporator in there. I'll get to it one day.

Also, I don't think blocking the side vents on the splitter changed the flow- the fan just seems to go faster on a/c mode. Removing the evaporator should make a little difference tho.

good thoughts tho.

thx
