So it looks like I have the 500 airbox parts but need the 4 rubber pieces that connect to the carbs, 2 vent lines, a grommet between the air box and the air filter box, and an air filter. Do you all buy parts from that site or just mostly use it for reference? I have sent PM's to both wowbagger and 78550 but also just want to know where to go for this kind of stuff in the future.
