Thanks for the info, that kit is no longer available .
It's stated that there is a nut on the inside of the glass, none of my speedometers has that or the screw not even visible inside the speedometer .
Got the parts yesterday, looks like I have a plastic rod that will fit into the button and I'll try a bit of clear sealant to secure the button to the glass .
I just want to prevent water from getting into the speedometer, if the trip odometer can be reset great but not necessary .
