Thats cool. I was just on RA looking for some motor mounts last night; funny thing is that despite choosing the same body style and engine; different selections gave me different mounts. I was looking for mounts for a 70 B body (Roadrunner, Charger, Coronet, etc.) with a 426 Hemi (also tried E body, Challenger and Cuda). One selection gave me what appeared to the the right side (its very unique with 2 studs on one side and one stud on the other) and listed like 4 variations of the same mount (despite saying one was right and one was left). Then another selection gave me what appeared to be the LH side (which looks more like a conventional wedge mount). I ended up ordering one of each and just received the LH side, it is incorrect for the application but for $3 I will keep it.
