This kit includes two special length bushings and two special o-rings which mount between the bushings. These are installed in place of the original Webster bushings. This kit fits Webster Mk9 and Model 400 bearing carriers made up to 1999. Webster bearing carriers after 1999 can use the new style Webster Selector Finger Seal (Part No. 1410-A20-9), which presses into the back of the carrier.
We also carry an External Shifter Seal Kit (Part No. 1414) which can be installed on either Webster or Hewland bearing carriers.
