Get the service manual that the vendors sell. There is no order but search through and find the needed pages. I totally redid the ac on mine 2 summers ago. It was a basket case. The PO's rigged all kinds of stuff. But I found everything in the drawings. Also both of mine that have been converted to 134A have blown the hoses so you might have to replace. I was told combo of old and not used in a while and 134A runs at higher pressure
