Hi Olan
Welcome to the R65 website.
There are a number of parts websites available on line, the one I use most is RealOEM.com.
Before you go there, get the last 7 characters of the bike's VIN (vehicle identification number), or serial number however it is referred to in your part of the world.
After entering the VIN, at the bottom it will give you the date of manufacture, it is sometimes required, as there have been a few changes in parts used during production, that will be noted with the part number as well.
It's not to difficult to find the parts you are looking for, but sometimes they are not located where you think they should be.
The part you are looking for is the sheet metal 'panel' ( that's the official nomenclature in the parts catalog ), that also has the tubes to mount the turn directional housings and lenses.
The part number is : 31421235573.
Hope it helped you out.
