When I bought mine from them, I talked to them personally.... there were two different mfg's of the shelby hood for a 67 without the special fender pieces (basically a regular hood with the shelby scoop). He recommended the one that would fit better but needed a bit more 'surface' work to prep for paint. Obviously the other one they had had less surface prep work, but the overall fit was a bit worse and required cutting of the actual hood.
SO, just talk to them and they will size up what you require and make a great decision for you. I also got the orginal tooling fenders and the california special trunk pieces... again on their warning, the trunk was a great fit, but the quarter extensions were horrible... not now, but they took alot of work.
