Does the AC compressor have those metal washer o-rings in the back where the hose goes in, in the back. The input and output ports on the compressor's back side. I pulled the hose off and didn't see any on there so think it doesn't have any but just wanted to make sure before it's put all back together. I was thinking if I pulled the hose and they fell off where I can't see them it'd be a pain to have to do it twice.

This is for a 1999 3.8L Camaro but I looked at pictures of the 5.7L compressor and it has the same looking holes in the back of the compressor so this question could be answered by a V8 guy

Thanks guys!
