Front valance

Don't toss that valance until you have another. They are extremely hard to find. You are looking for a 64/65 Barracuda. I have seen a 64/65 Valiant valance used with slight modification. Valiant's had the turn signals integrated into the valance. You can cut away the turn signal mount easily and it looks good on the Barracuda but not original if that matters to you.

There is currently only one company that I know of repopping this part and it is only in fiberglass. They tend to take a beating so unless you don't plan to drive it on the street, I'd look for a steel replacement.

They call is a "lower grill pan" ? If they called it a valance, they might have more people find the part.? Lower grill pan? What?

If someone would make this part in steel, they would sell a bundle!
