I bought an O-ring kit for my 71 chevelle, but no idea all the locationd they are located. Also some are green some are black..any difference? is there a diagram somewhere i can dowload showing the locations?
Every connection will have a "O" ring or seal of some type. The newer type "O" rings that are compatible with R12 and R134A are most often green but some are black also. I have no idea where to find a diagram for that other than a GM manual. Back then the manuals weren't that good, I had one for a '78 Corvette that didn't give much detailed info.
This is sounds quite interesting, thanks for sharing it.
