Lost Bolt for A/C compressor lines

[Guess]

As careful as I was removing the driver's header, alt and compressor, I lost the bolt that secures the A/C lines to the back of the compressor. Anybody know what size and length of replacement bolt I need?

dunno, but i'm sure they are all over the junkyards in pretty much any GM car or truck that used that style of compressor.
and you will find that bolt- about 5 minutes after you put in the replacement bolt.

Yeah, I'm going to head out to the parts store and buy about 3 different sizes close to what I think it is.
