08 Ridgebacks had the super long bars on them (lots of Pullback). The early Chopper bars have about 5" less pullback. You may want to look for some bars off of a K-9 or earlier Ridgeback (something in between).
I've got a new set of 05 Pittbull bars and they don't have much pullback. Basically they are identical to the early, short Chopper bars but they are about 2" taller.
