Factory/Dealer installed trailer hitch on a 1970 Dodge Dart?

yep. my 70 dart came from the dealer with a trailer hitch...it was a factory 225 slant six car, with an 8 3/4 rear!!! pretty rare combo for a slant six car to come with an 8 3/4. :)
i took the trailer hitch off and threw it away.......was it worth anything???

I parted out a 69 4 door Dart- slant 6- with a tow hitch- guy used for towing boat...- bolted to bumper brace and to spare tire floor
