What I was trying to say is if you buy the OEM parts needed for the conversion, Upper control arm, spindle, hub, rotor, caliper, lower control arm (not sure if you need that), hoses, and pads from an appropriate year to get you 5x4.5 BBP and discs, then you will only have to remember that your front end parts are for a (I'm just pulling this date and car out of my butt cause I don't recall the change over date to 5x 4.5 BBP) 1975 dart, duster etc
