Those who have '92 - '96 & '97HD F-Series know if you have a rubber seal that seals around your trip meter reset and trip meter / odometer selector buttons? A seal that would keep dirt and dust out of the inside of the speedometer cluster display.

 

No seals on any of mine and I have sold 20 Plus clusters over the years

 

dust is too scared to ride with me so i do not worry about dust in the cluster like you do.
