I need to purchase a new compressor for my 93.
Where does everybody recommend?

Does any one know the size of the bolts that hold the compressor to the mounting bracket?

Thanks guys!

It's a 10mm head, not sure of the thread size though. I got my compressor from Car Quest.

Did some searching and found it on the Web for $100 cheaper then my local Carquest. I would like to buy local rather then the Web but $100 is a lot of cash.

Johnny, I thought mine was 12 mm head, can't tell anymore, I broke all 4 off and the pump is seized to the mount on the donor truck hence needing a new one. Gotta love the rust belt

Yeah, a $100 is a lot of cash to throw away. My girlfriend works there and gets parts for cost so it wasn't that bad for me, still $230 or $270 I don't remember.

I got mine from rock auto which was 200 dollars cheaper than a local one

The bolts to hold the compressor to the mount are a metric thread...I want to say M12x1.25...but I'm probably wrong. A 5/16 bolt will thread in with a bit of resistance if that helps narrow it down.

As for A/C compressor, I got mine form these guys..

Thanks cows, I did look at those guys before I posted this. The only thing is, they list 3 different compressors, at 3 different prices and different part numbers for each. The only difference I see is one is a reman. I'll have to email them or try to call.
Thanks again for everyones replies

Johnny I stand corrected, found one of the sheared off heads and its a 13mm

IIRC, I discovered that the mounting bolts are M8 and I forget the pitch but the intake manifold bolts are identical.

I called up 1800-Radiator and told them i needed an A/C compressor for a '92 Dodge truck with a 5.9L Cummins diesel. Price ran a little over $200 I believe.

That may be a replacement already, I know mine has the 10mm reduced size hex with a flared head. 13mm sounds like a common hex size for a 8mm shank bolt. 5/16 and 8mm are virtually identical in size.
