rrc..does anyone know if..?

if..on the front swivel ball the oil seals that keep the diff oil at bay fitted in the axle end of the ball are the same on,

a 1972-86 six bolt swivel that takes 10 spline shafts and on 1994 7 bolt swivel that takes 24 spline shafts..??

reason for asking .uprating axles to 24 spline diffs with lsd's in them...done the rear..(a git as later type all metric and my axle cases imperial...and (oh bugger) oil filler on case on 24 spline and on diff on 10 spline..bugger..

thanks
