Ah, so that's a home jobbie, I figured the factory added that later on, I believe these pedals were from an 83 SX/4, the one that was in the 81 didn't have that stiffner on it, and the u broke off. I took a different method to fixing the issue, lol, call it a permanent fix.

Made a whole new post, and bracket.

Eliminated the U, drilled one hole, and the bracket bolts on the pedal, yes, it adds some heft, but it will not break again, lol.
