Jeff, Thanks for the pictures, and the info about which scoop is the early and later version.
Jeff & Randy, Thanks for adding to my education!
I'm now reasonably convinced that the early hood version had the deeper scoop opening like the gold hood Jeff posted, along with NO "gussets" under the leading edge. And the later hood version had the shallower scoop opening like the blue hood Jeff posted, along with the 4 "gussets" under the leading edge. Does anyone disagree with that? Have I gone off the rails with that generalization? Maybe those two features do not need to be linked to each other?
Also, has anyone linked the clocking of the hood pin plate rivets to these two hood types? Could the 12-3-6-9 clocking go with the early hoods and the 2-4-8-10 clocking go with the later hoods?
Steve
