If you're wanting to replicate the original 8V induction that was optional on the Cobra, the intake is one of the cheap parts. They're not uncommon as Ford also sold them through their parts catalogs. Hardest parts to find are S&H air cleaners, choke and proper linkage.
Carter AFB with correct numbers/date code are fairly rare as well but do come up for sale from time to time.
I'm in process of putting an accurate assembly together right now and have over $3000 invested.
