Console mounting.
Much thanks to ALL and especially you '67 for the pics and details. I see the obvious right there in your main pic, the rear slot is centered as is the recess in the stamping itself. If you look at the pic I attached, you can see mine isn't. I took same type
measurements and didn't come up uniform like yours did. I will make adjustments as needed but can now sleep at night.:lol:There may be some other imperfections but I'm sure this was the main culprit. Thanks again, this site Rocks!
