Can any one confirm the correct method of securing the A/c compressor tag and the A/c clutch feed wire, these are secured on top of each other. So far as per the Jim Osbourne 1970 body book, it calls up for a clip, other books that I have seen and also various other pics shows a bolt. Which is correct? or do different assembly plants have different methods? If it is a clip does any one know what it looks like? HELP
