Own a 2002 GL1800. Have been trying to find out the name and address of whoever manufactures the internal mirror inside the LH mirror assembly. I am pretty much running into one dead end after another and can't find a way to buy just the mirror and not the complete OEM assembly. Have even struck out on salvage. The mfg part number for the mirror alone is 78393 and the plastic part it attaches to is 78401. I am pretty sure these parts were manufactured separately and probably by one of Honda's outside vendors around Marysville, OH. Need a starting place to contact who actually made the parts for Honda so I can contact them direct. Previously, another good Forum member suggested the Muth mirrors with the LED turn signals and this was a very good suggestion but they cost almost as much as the entire assembly. Thanks for your help and any leads or ideas about how to find the supplier of the mirror.
