67 formula S 383 4 spd

X2 with what pettybludart said, pics is a definite. BB formula s is getting rare, but you gotta take into acct the inner fenders being cut out as well. Do your homework on it, as with any vehicle purchase, the more research leaves less room for disappointment. In my opinion a BB formula s notch would be rarer...but thats my opinion.
