Like most early A sheetmetal, trim and interior parts, the 66 column shift column is 1 year only as is the 65 style for column shifting. They are not made of unobtanium but close to it. Put out a Want Ad; you never know wgat’s Hiding in someone’s parts stache. I think I might still have the engine compartment linkage from a column shift slant 66 Barracuda I parted out years ago.
The oil pan/pickup will work from a slant 63 through 66 will work.
