Duster Hood Question

I'm thinking about a new hood for a 1970 Duster and I'd like to go with fiberglass. I've seen a few different styles, but my question is about the cowl induction. I can only find a 4" cowl option, which I feel is too high. Does anybody know if there is a 2"cowl fiberglass good being made?
Thank you
I special ordered a fiberglass hood w/ a L88 cowl ind. scoop in it, for a vega. Don`t remember what company, shop around till u get what u want !
