I can't find in any references that I have as to curb weight. Can anyone else help him out?
I know one thing, my 72 is HEAVY with or without the RB

My very first car was a 72 RR...but I didn't get the one I initially wanted. I had ordered a 1972 Roadrunner in March of 1972 and it would have been Basin Street Blue (which is Petty blue to ya'll) with a 400 cid and auto/slapstick and black roof strobe. It was suppose to be delivered in 6 weeks. After about a month I got a letter saying my order did not make the cut off for 1972 and I would be getting a 1973 instead.

I really didn't want the 73....there was something about the B-bumper on the 71-72 that just got my blood flowing. So, I had my dealer do a search on all the remaining stock of 72 RRs he could find. He got me a white 72 bird with a 340/buckets/slapstick/airgrabber car out of Idaho. It had the hood/deck stripes that were only available on airgrabber birds (and Satellite Sebrings). I loved that car, but I always wished I had gotten my Petty blue bird.

My current 72 RR is blue....Viper blue.

You do know that the 72 RR is the rarest of all birds, which is one reason they are so hard to find, right? They made significantly more 71's and 73's than they did 72's (less than 7,000). The first year of the smogger engines really killed sales in 72.
