Alas, no taillights or hard to find bits, but, the 427 and excellent 289 are both there, seats are stock, firewall and core support are there, chassis that has no exhaust is a plus and in the box. Rear bumper will swap, front can be separated from the blanked grille to save a promo that lost a kitchen floor demo derby.
I believe many of the parts can sub in for any '64 Fairlane 500 Sport Coupe annuals that fall your way, either as rebuilders or beat up promotionals.
I've grabbed a few '65 Mods for some annuals that I snagged from shows and online. Might have to see about a few more.
