Need help-advise

Welcome to FABO. I believe you will be able to use Dart / Valiant / Scamp front rails and suspension goodies, possibly inner fenders will match up as well. However, fenders are not reproduced and kind of tough to come by, not cheap for real nice ones. Shipping ads to the dilemma due to size. Header panels are "comebyable", but the grill is a search again. Not trying to be a downer, but these babies are challenging builds. Rust free body is a nice thing, nothing I have is! You have your work cut out, but you'll have a very nice car when completed.

Well, fenders were just wishful thinking then.
That was off the top of my head.
I'm always surprised and what can and can't be found for "these cars".
I'm finding things for a first generation Charger that I didn't think I could find.
But other things like quarter panels.....no luck.
I figured it's a desirable Barracuda, maybe they were repoing fenders.
