I'm installing the 6.1 MP kit in a '71 RR and using the wiring harness that came with the kit. (This is not using a 5.7 or 6.1 that came out of a factory car)

I have a question for anyone who has done this. Do the alt., a/c compressor, etc. from a 5.7 Hemi fit and work on the 6.1Hemi crate? I purchased the 6.1 MP kit and need the accessories. Since almost all of the install into a '71 RR has to be fabbed up, will the 5.7 components work on the 6.1 accessory plate that comes on the 6.1? I'm thinking the same front setup comes on both engines?

Thanks!!!
