Yes, I understand that bracket is ONLY for B Bodies, and I'm not saying anyone should try to use it on an A. What I tried to point out, is that in addition to raising and moving the shifter rearward, that bracket ALSO tilts it back, so that the shifter is completely upright when in neutral. If you install the 71-4 Bench shifter without that bracket, it is tilted forward, as seen in all the pics people have posted on this thread.
To use that shifter in an A body, and have it oriented as it should be, one would have to fabricate some sort of adapter that would tilt it back about 20 degrees.
