Default Size of A/C compressor rear brace bolt

I just found out during my head swap that my compressor doesn't have a rear brace. I bought a brace off ebay but they didn't include bolts. Does anyone know the size of the bolt that goes into the block? I tried 3/8-16 and 3/8-24 with no luck. Does it have some funky thread spacing?

The bolt into the block should be 3/8-16 x 1.12. Maybe your threads need chased. The two into the compressor are metric M8 x 1.25 x 20.

Seriously. He called it perfectly again. I was hesitant to chase the bolt hole in case I picked the wrong size but I used a 3/8-16 chaser and basically started a rust avalanche. Now that all the rust is out of the bolt hole, it works great.

Thanks shoebox. Whoever... or whatever ...you are.
