Ah the Great White Buffalo Hunt

I have only seen 3 cars EVER that have had this option and have never seen an actual FC7 car though one was used for advertisement and I have seen an original rear bumper.

Of three I have seen they are:

EV2 - JS23V - automatic Canadian car that I own
GB5 - JS23V - 4 speed - I believe this car was ordered with bumpers but delivered without and then added at the dealer, Grand Spaulding Dodge
GY3 - JS23H - this car came out of the Bay Area and at one time was owned by Lane Rivers, I'm 99% sure it was an R/T

All of these cars are M73. Another cool question would be are there any M71 (front bumper only) cars out there?
