Looking for someone who followed the Rod Shop Challengers as I have a pair of Lexan glass side windows that may have come from the 73 Rod Shop Challenger...or so I am told.
I've been researching old pictures on various forums but can't seem to match the numbers on the glass with a car

The 73 car spent some time in upstate NY which is where these came from, and then I believe went overseas.
I believe the pre-fix 1 indicates NHRA but could be wrong

B/O on the passenger door glass indicates ?
Drivers door glass has these other set of numbers 581-0732

Thanks in advance for any help

Is that B/G or B/O?
B/G is for the class, B Gas.
B/O is Best Offer

If B/G, the 1995 is a NHRA driver number for Divsion 1, "Land of NED", North East Div.
The Rod Shop was in Div 3, "Land of the Winners", so a driver number would have been 4 digits beginning with 3.

If B/O, the 1995 must be the price.
The 581-0732 is probably a phone number as driver numbers and class should have been on both sides.

You may be on to something there on the numbers.
Definately looks like BO but I cant see a car like that being offered for $1995.00
Thanks for the info
