    Rocket Seal here in Denver believes they have a fit at $1.27 each. So I'll plan on paying them a visit.

    May want to try to find hydraulic hose for this. Oil/grease usually will soften and swell a typical 'coolant' hose material.

    I like your idea of slicing a hose. Its not really a seal anyway, more like a dust cover. I have torn down many front ends with some of these seals missing. As long as you keep it greased every 5000 miles or so, the slices of hose should be more than adequate.

    SI shows 525035 upper and 199385 lower. As loose the uppers that the sent fit I think they really sent me lowers. I'll call.... thanks.

    Which seals are we talking about?
    one poster referred to the seals between the threaded bushings on the outer control shafts on the "A" frames and another
    referes to the seal on the bottom end of the kingpin.

    Thanks. I'll try Whistler Bearing Supply. Good point on squeeze pressure.

    My rebuild kit from SI had regular "O" rings. Make sure you have about .004"-.007" of "squeeze" for a good grease seal, otherwise the grease won't reach the upper part of the kingpin & bushing.

    Or go to your local Bearing Supply Store and buy some "O" Rings they can replace the square profile Seals that Studebaker used.
