Hi GS family, I am having trouble locating the proper oil adapter for my 1968 GS 400. It is leaking and I cannot find a gasket for it. I ordered this part ( see link below) but when I held it next to the part on the car it does not look exactly correct. Seems like my part on the car has five bolts and this adapter only has four. Plus I do not understand what the "METRIC" stamped on the new part is. Any suggestions?
