A 1974 Duster - My 2nd one, 41 years later!
Thanks trebor75, thanks Richard. I am NOT going to cut into the inner fender to do this install. It will go back to Summit if it doesn't fit right. Seems like it should say "Doesn't work/fit with an A body". I had to try but really don't want to cut up the inner fender.
Sent the American Powertrain Hydramax clutch kit back to Summit! Gonna go with the good old 12 1/2 clutch fork set up. I'll do the z-bar mod and re-weld it as needed to fit the Dougs headers.
