Sold both of the Barracudas & moving on to a B-body

Probably a 1964 Plymouth Sport Fury, Fury, Belvedere or Savoy.

You might try Jim Hale in Van Buren , Ark. , he`s a 64 nut now , or was. He had about every 64 Plymouth body style and engine combination made , at one time a few yrs. back.
His stuff is usually first class too !
