Proper plating for hardware - J52 balance valve bracket & bolt @ '69 SS

[william]

This is an old thread. I thought my bracket was damaged that holds the metering valve but Johns looks exactly the same with that odd stamp in the top of it. I was hoping to find a new bolt since mine is pitted but I guess no one has this bolt. I checked amk and heartbeat city and neither show it.
Part number 3848408

3848408 was also used to retain the coil bracket on sb/bb. Shown in Section B9 page 6 of the AIM. Should be plenty of those around. Anyone have a parts car?
