HVAC - Automatic Climate Control Unit

[lino]

As I've mentioned in other threads my car is a US spec 1991 Q45A and the Automatic Climate Control Unit is diplayed in Fahrenheit. Since I live in Canada and Celcius is used here, I thougt it would be better to have a Canadian part. I was thinking I'd like to buy a Canadian part and have it sent off to Jerry Tucker's All Import Service and have them rebuild it and then I can replace it.

My question is what years will work for my car? I found 3 cars in a salvage yard that still have the units. One car was a 1994 and it looked different. The othet 2 looked the same as mine.

Mine looks similar to this one:
