I could get you a hard price but it won't be cheep. But if you wanted to go that way then you might as well go all the way and add in cowl induction.
I just talked with Jeff, my fiberglass guy that built the body for my build truck. He would need to make a mold from the hood I have 1980. So that would require some light body work to get it ready to make a mold from. He needs to know if you only want a skin or do you want the under structure built into it. If it was a skin only then it would be a lot less expensive. But with under structure it would run about $2200.00 plus shipping. But then you own a mold to build and sell more from.
