Good question. I've seen plenty of fake BB 69 Camaros with
the oval hole X-member. However, every real BB 4-speed I
have ever seen has the squared-off hole.

I actually never did get a real good answer as to why the
BB 4-speed X-member exists anyway. Aside from the hole
difference, and the large dimple on the upper passenger
side, they appear to be the same. What is the actual
positional difference of the transmission in conjunction
with each of these X-members? Surely someone here used a
SB X-member on a Camaro once.
