Good info here Gents on a much over-looked topic. Allow me to add a little more:

The OEM shifter mounting holes are different relative to the tranny mounting holes on big block xmembers. They are offset to the left about 1/4" compared to SB. This allows the BB shifter linkage to align correctly. Yes, a mismatch will work, but thats not the way they were from the factory.

This applys only to 67-8 Camaros.

69 only has a similar issue. The shifter rods are about
1/3" longer to accomodate the mounting of the shifter with
that special ( again, BB only ) horseshoe mounting plate.

69 BB's have lots of these accociated issues. The lower
reverse lockout rod is also different for BB 4-speeds.
The flat nut for the Hurst shifter adjustment is a racetrack
shape vs. the rectangular shape of the SB's. Once you start
you just can't stop.
