IMHFO, just that, an opinion... for a clone/tribute the bolt ons/hinged types probably won't be very accurate as far as under-hood structure & authentic looks...
I've never seen or dealt with the Penstar's can't really say how good they may be....
AAR Fiberglass
VFN Fiberglass
US Body Source
Harrys Glass, they may have carbon Fiber too
Sled City, but has some bad stuff about delivery times & alleged health issues, small crew size, supposedly/allegedly causing the lengthy delays...
Fiberglass Trends, if they are even still in business...
IIRC they all have the fiberglass bolt on hoods, not sure which are the most authentic looking or closest to being correct,
like the real style "Lift Off" A12 {4 Pinned 6bbl} Year One Hood is the best I've seen, for looking much like the real deal...
The accurate 69.5 base for the air cleaner to seal to the hood so you get actual ram "cold air" induction, maybe an issue too, with the ones with-out the inner structure under the hood, like the originals or Year One A12 reproduction hoods,
the OEM style factory ones, are really pricey, more than you'll pay for a hood...
But there is a company
http://www.hybrid-fiberglass-solutions.com/products/standardbaseplates.html that make an "affordable" fiberglass reproductions of the "original" steel ones on the 69.5 A12,
but in fiberglass
Anyway good luck with your A12 Clone/tribute project...
