A-body 4 speed questions

Hello,
Do all 4spd pedal assemblies interchange between years (i.e 68 fit a 71 and vice versa)? Is there a difference between auto and 4spd trans crossmembers? I'm a B/E body guy, so I'm not up to speed on the interchange..
Thanks!

pedals are the same , maybe a slight visuual difference but they fit and work the same .

same crossmember for either trans

I believe the pedals mount up the same, 67-76. These are 68:

Thanks, guys. Chief, do you have a pic of the other side of the pedals? Is there a square flange that is parallel to the ground when the pedals are installed? Thanks again,
Danan

1970 and up pedals will have the neutral safety switch on the clutch pedal

I think you're talking about the third column mounting point/bracket, as pic'd.
