I just spent a ton of time searching for o-ring part numbers, then (finally) I realized it’s easier just to open all the diagrams in a browser window and hunt from there. These are links to all the BXA diagrams I found on the JimEllis site––which seems to have the best diagrams. Shout out to them. (However, I found that audi henderson and new orleans seems to be offering heavy discounts at the moment)
