I found this site that has parts. Says its $25 + shipping.

I just did a Google search for odometer parts. I just found the first site that had the part, you might be able to find it cheaper somewhere else.

 

will this fix both my odometer and trip meter

 

Yes it will.

 

is that a good tutoiral to use for fixing the odometere or is there a better one

 

Yeah it looks pretty good. I actually took the blue retainer out, its just held in with a few small screws. Once you get a look at it you'll figure it out. Getting that "worm gear" (the one with the motor on it) out can kinda be a pain, but I doubt you'll break it, but be careful anyway.
