If you're rebuilding your Sprite-Midget ribcase transmission, this is the kit you need! This kit contains all of the wear items outside of any worn gears. You get all of the gaskets, bearings, layshaft and seals required for a top-notch rebuild. Kit contains:
  • Full gasket set
  • 1st and 3rd motion bearings
  • layshaft and layshaft bearings
  • baulk rings
  • rear bush and rear seal
  • bearing shims
  • locktabs
  • needle roller bearings
I have examined your 1275 rebuild kit but I think that I would also need the small springs, plungers and balls also.
