Manual Brake push rod needed

Are all of the manual pushrods the same, then? I mean, is a '70 Duster the same as a '74 Dart Swinger the same as a '67 Valiant, as long as they are manual and not power brakes? It doesnt matter if they are drum/drum or drum/disc?

yup they even interchange back to 1966,,maybe back to 62 i would think,but not sure. you can buy a adjustable push rod from mancini,,but it wil need to be cut down,, at its smallest adjustment its still too long
