Been hitting this on and off for the last month. Finally decided to hack up an EDEN LH 21 fret neck this AM. Head stock is a work in progress but I think it somewhat relates to the original TBird. Standard Fender headstock will also be available.

Nekkid as a JAEbird
Going to use Hipshot ultralite clover tuners with less of an angle than this. Pickguard will get a slight reshaping where it's tight to the cutaway.
No problem reaching ALL the frets. Reshaped neck heel, belly and arm cuts too. Fly optional.
Splendor in the grass.
Don't worry Jim, yours will have a RH headstock and 2 pups, only 20 frets though.
