Photo request: Brake linkage

[SchreinerM]

Hi guys, I must of missed this area when taking tear down photos however many years (and years and years) ago I pulled the booster off the truck. Does anyone have any photos that show how the linkage is all hooked up between the booster and the firewall?

Obviously the linkage in the center of the photo slides down between the booster / firewall brackets. But which push rod attaches to which linkage hole (meaning does the rod from the interior go to the middle hole or the bottom one; same question for the push rod from the booster). And I assume these connections use pins with cotter pins (not bolts). Is that correct?

Thanks!
