I want to replace my 1974 Roadrunner front rotors with ones from a 1970 Challenger. Does anyone know if this will work? Any problems with spindal diameters? I don't have any info on inter changes between these cars. Thanks.

1970 Challenger were a single model rotor which means they are more expensive to replace, most Challenger/Cuda owners usually go for the later rotors as they are more inter-changeable.

A '70 Challenger has the "small bearing" spindles, '73 and later are the "large bearing" spindles...the rotors won't interchange.
