74 or 75, is there a difference?

I agree with Mr. Mo that most harnesses are the same depending on engine and A/C. I own a '76 Duster and I'm also finding that most of the aftermarket seems to have a prejudice against the '75 and '76 cars, even though almost everything will interchange from '73 and up. I too plan on doing a V8 swap in the future and will be purchasing a '74 V8 harness. Good luck, Mick.
