I am trying to mount my sons AC compressor back in his car. I have the long through bolt, that is at the top and closer to the middle of the car. I have the bolt at the bottom that slides through the bracket to tighten the belt, but the bolt that goes to the top pivot point I must be missing. I have a bolt that I thought was it, but it will not catch the threads. I'm thinking it's too big. Anyone have an idea what length and thread size that bolt is? I just might as well buy a new one.
I used a single long M10 bolt, 1.50mm pitch, 160mm long. Mcmaster has them for $8.62 for a pack of 5.
I think from the factory they use two short M10 bolts but this is much harder to install and remove. The single long bolt is very easy to remove. If you go this route consider getting the 180mm bolt - the 160mm works but only engages about half of the threads on the compressor.

There's no way. That's about 6 inches long. (I think) That' way too long. The one I'm talking about is on the belt side, top bolt. It can't be more than 2 inches, give or take a few. The bolt at the top on the starter side is probably this long, and I have that one.
That's what I meant. The factory uses two short bolts, one for each side, but this makes removal and installation really difficult when the compressor is installed because of the limited access. Instead, I opted to use the single long bolt that picks up both ears.
But the threads cut into the a/c compressor would still be M10-1.5.

So masospaghetti, should the whole thing be threaded or do you need to drill out the threads on one side? If you use two how long are they, 20, 30mm? Seems like two, pita though they may be, would be tighter.
The inner compressor ear is not threaded. The bolt shank will pass right through it. I guess they install a nut here from the factory?
You don't have to drill anything. The long bolt will pass right through the inner compressor ear and bracket and thread into the outer compressor ear. The whole thing will pivot, which is what you want (to allow adjustment for belt tightness).
I've been running it like this for a couple months now with no issues.

That's exactly how it would work. A great idea Maso, but I could only find a bolt from Fastenal, and it cost $20 including shipping, so I just went with the M10 1.5 thread. It's all in there and good now. That bolt is a ***** to get in, and then even worse to tighten.
