Odometer questions...

I have a 94 KDX 250.. I'm in the process of putting it all back together (fork seals replaced.. engine rebuilt) anyway while I was putting it back together I decided to remove the odometer because the cable was broken and I really have no use for it anyhow... I removed the cable on the meter gear housing (front wheel) but now there is a big gaping hole where the cable used to fit... I don't want dirt and mud to get down into the housing for obvious reasons and I also don't want to mess up the hole in case I decide later the odometer was a good idea... any suggestions on something that will stay in place yet be removable later?

Also after I removed the odometer there is now a big empty place where it used to be... I would remove the whole bracket but I found it has two uses, one of which is to mount the front plastics.. is there an after market bracket that I can use to mount the front plastics on and remove this eyesore all together?

Thanks for any help

Thanks for the info guys that Ty Davis site has alot of cool stuff... I will end up going to the auto parts store and finding something that will be of use I just thought maybe someone had done it and had an exact part so I didn't have to search so hard... I'm very lazy... As for the mx # plate I leave the headlight unplugged until the sport bike races come through Atlanta, then I hook it back up because they let you ride your bike around the track's infield as long as it has lights... makes it alot easier to get from one side of the track to the other when the race starts up...
