This post prompted me to see if I could maybe get my hinges to function better since they auto- close and then rattle in the near close position. Last couple years I've used tennis balls to keep them open. Unfortunately, I found the pot metal was cracked and it came apart in my hand after barely touching it, For now I'm attempting a JB weld fix to least keep it together while in the fully closed position.
I assume the older, chrome style hinges should also work in my later '75 model?
