I bought the bash plate/toolbox combo soon after I got the bike in 2008. It's a nice, well built, if expensive bit of kit unfortunately with one draw back - it is a arse to get tools in and out because the lid only opens half way due to the exhaust header on the left (not an issue on KTM Adventure, which was the bike this part was actually designed for). I modded mine with clevis pin and R-clips to make the lid quick release. This has saved my knuckles being skinned whenever a need to find a tool.
However, I'm working on a slightly more refined quick release lid system as we speak. Watch this space...
Note - nylon washers are superglued in place on the lid.
Oh, nearly forgot: It is worth sealing the four holes in the front (spray from wheel gets in) with silicone from the inside before you fit it, leave the lower two open for drainage (water doesn't seem to get in here).
