Can I be your 3rd son...??? :lol:
The sponsor on this board, broncograveyard.com, has columns & a 2% discount.
Sounds like your 3 sp. column was re-rigged to shift an auto.

Columns can run fr. $400 up to $1000 depending on what other piece-parts are needed. (high end being "tilt" columns)
I had a similar messy set-up on one veh., so I left the column in & installed a cable driven floor shifter between the front seats. It worked fine & was under $200 as I recall.
When eng./trannie/transf. are swapped., there's usually other changes made.., like the dr. shaft lengths & the transf. case crossmember mount, as Bronc76 mentioned.
Do you know if it was orig. a V/8 or was it an I-6..?
That's likely a Ford 9" rearend if it's stock....
