When I posted earlier the passenger side was off and had no markings, once I got the drivers side off it was different and had the markings that you posted. Sure enough I measured it, and it was on the high (11.090). The passenger side is 11.170" so I am going to replace both sides. I can see the "homemade" looking rivets on the driver's side so I know it was replaced at one time or another. Maybe the passenger side (that has the minimal markings) is still original?!
Thank you so much for posting the photo! I appreciate it!
