Default ECM bracket hardware

I need to replace a broken "bolt" on the bracket that holds the ECM, on my 1993 LT1.

The "bolt" is actually a U shaped clip with a half inch long bolt / stud, which accepts a 10mm nut. There are three of these that secure the ECM.

I can find plenty of U nuts (the female version of this item), but cannot find the needed male version. I also cannot find a GM part number in the FSM.

A page from the FSM is provided below with the item circled in red. I also provide photos and close ups.

Can anyone provide a part number, or a suggestion for where to find these?





Close up with nut attached





Nut attached





Close up with nut removed, and ECM tilted up from normal position.

The GM # for the hardware is 12337892 and can be purchased nearly everywhere even Amazon. If there's a salvage yard/JY in the area it's used on nearly all ECM brackets, radios and other electronic devices.

The thread is actually M5 X .8

I would think still available and on many dealers shelves.

If this link works it would be #5 in this image.
