Hi everyone. First post here. I've had my 93 explorer for over a year now. the ac hasn't worked since I got it. it needed a new compressor. So I bought an accumulator, compressor, orifice tubes and both lines. I took the old compressor off months ago and have moved since then. I lost the bolts!. I know this is a dumb question. Can anybody tell me the size of the 4 bolts that bolt it into place and also the size bolt that bolts the line to the back? And also are replacing the old parts with the parts I bought enough to convert from r12 to r134? I'm going to have it vacuumed and charged at a shop. Thanks for the help!
