I am restoring a 72 Stage 1 with AC, and the original fan and shroud were missing when I bought the car. I've been told that it should have a 7 blade fan but none for a 455 is shown in the assembly manual. Anyone out there know the diameter,# of blades, part #,etc. for what is correct on this model. Can I assume that the shroud is the same as other GS 455's? Thanks, Mike
