What is your car's rarest option?

Nothing super rare on a 340 swinger, but all the options combine made it a pretty special little car 340, 4 speed, sublime, go wing, Hood treatment, torque boxes 8 and 3/4, rally dash if you put them all together it's pretty much a one-year deal. The only thing left for 1970 was a six pack only available on the TA so I just had to get one of those.
