Bottom A/C compressor unthreaded holes vibrating

[TX87R10]

I found the source of my vibration at idle and it's a missing bolt or smth in the bottom of the compressor. It seems like the hole extends all the way across the compressor to the bracket but there are no threads anywhere.

I searched far and wide and I think there is a bolt of same sort with threads on both ends and a fixed middle portion to separate the threads and probably nuts of some sort on both ends.

I must be bad at searching but does anyone know the bolt that should be here? The only diagrams I am seeing are for the larger style comlressor

The bolt is not a standard one it seems #13 in this picture. Haven't found a part number for it yet that checks out
