I just cracked the cast aluminum air cleaner base on the 1984 VF500, attempting to reinstall the carbs. I've found a 1985 air cleaner base on ebay, BUT, according to Bikebandit, the 1984 is a part number 589062 and the 1985 is a 589063. Would the 589063 work on my 1984???
You need to know the actual honda part number, beaverdam honda (now powersports or something) shows actual part numbers. See if the earlier one supercedes to the later one.
