I came across the two units today -Stage I and Stage II

 

Stage I comes out the opposite side and from the quick look I gave I'd say they will not flip flop over.

 

Parts manual says "Not interchangable". :-\

 

 

Todd-it's your lucky day !

I ordered one from the E-Bay site that Todd showed and the guy there is very helpful and nice,,,He's glad to know he could help us out. Give him a call. L.C.

Just an FYI.....the 79-84 Dodge Colt/Plymouth Champ heater core can easily be made to work on Gen 1s. (I think many of the Mitsubishi/Dodge brand from the late 70's to 80's will work too). These are easy to find.

so where do i get one for my 1975 subaru wagon

Check ebay.
