C-Joe almost got it

The shifter box is indeed a '69 Z28 Camaro, as is the boot and ring (black).
The arm however is '68-'70 GTO & Tempest, with a 4speed (can not be a 3speed), and a bench seat. The number on the arm is 4177. This arm may have been used as early as '66 in the GTO/Tempest. According to original owners, the ball was a black one piece as installed in the GTO/Tempest.
The attaching bracket is the standard SB version with 9 holes (not 7, although that version will work). This is somewhat unique bec/ the deuce has a BB trans x-member, but SB frame mounts, and a SB shifter bracket. Strange combo, but....
The rods are supposedly BB! I've not been able to confirm the part numbers of the 4 rods as such, but that is what I've been told. There are 4 numbers stamped into each of the 4 rods representing the last 4 digits of the part number (?). They are: 5775, 5776, 5777, & 5779.
Hope this helps.
