***where can i find a cowl hood***
105cuda, finding one is prob like finding gold imo.
I have a 66 Valiant, and there are very very limited fiberglass part for it as well, even more so than your 68.
But I am in the same boat as you and wish someone made a cowl hood that went to the windshield.
I think it's VFN fiberglass that makes a stock flat fiberglass hood for my car, so I plan on just buying that, finding a cowl that will work and look good, and either mating it myself or have them do it.
Good luck on your search!
