Are the radiators the same size for A/C A bodies vs non A/C cars. My 75 Duster has an aftermarket plastic tank radiator. It must have been installed when the previous owner removed the /6 and replaced it with a 318. Car had A/C Will be adding A/C back to car in the future. I would like to go with the V8 steel tank radiator at some point
 
References I found only go through 1974, but it appears there are possibly three different sizes. 19" for /6 with heater only, 22" for small block heater only, and 26" for small block with A/C. General information, so if another member has more specific details for 1975 please chime in.
 
Radiator type depends on the original application.

Do you have a broadcast sheet for it?

If so, what numbers are listed in the radiator section?
 
Is the existing radiator in the car 19” or 26” wide?
 
If your car had AC in that year, it should have had the 26" radiator in it.
