Yes, the cowl induction hood was legal for TA racing in 69(not available in 68) so GM made the normal metal cowl induction hood as an RPO and then released the fiberglass crossram cowl hood as a heavy duty part because it would qualify and save weight on the front end. I don't see the reason for the metal crossram hood unless GM was required to produce it to satisfy the SCCA. Obviously the metal crossram hood will fit better than the fiberglass hood because it won't tend to bow. But with such small numbers made(10 or less?), it has a lot of value to some people.
