Back to the party, I was thinking seems there are just two OEM items on my truck that are square, a pair of cab shims. The carb is mostly square though; a gray area, often written as grey.

Wait, those cab shims are clearly for the body, so, the unedgucated are actually right.

I took the picture from far enough back to hide the paint flaws. It's a nice 20/20 rig. And it has a square driver.
