Should you wish to embark on the Interceptor adventure of a lifetime, what could be more fun than resealing your own rack! For the adventurous at heart only! This kit is for both racks that came with MKII and MKIII Interceptors - HBD5151 and HBD9151.  They are similar externally but somewhat different on the inside.  You will, therefore, have a few seals left over depending on which rack you rebuild.  Please check each seal against the ones you removed to assure a perfect match!  This kit does not include the means to recondition the internal portions of the Valve Assembly.
