I wasn't aware of this until now, but one could delete the disc brakes on a '65 Corvette and receive a $64 credit...unsurprisingly only a few people did so (I believe the number was 316).
It's ironic that the seller is using the '1 of 316 original drum brake cars' as a selling point for a car that's anything but stock.
