Speedo gear still leaking

[Westex]

Have read all of the posts on this issue, and my speedo gear reducer, plugged into the transfer case, still leaks due to the seal INSIDE the gear reduction unit. I am exhausted trying to find said seal in this one horse town; anyone have a remedy? Stewart Warner is the unit manufacturer, and their website is Caca beyond belief.......gringeltaube in Montevideo posted some info on this in March of 2009, but I'm unable to extrapolate the information to the U.S.

Allright, well, I pulled myself up by bootstraps. Southwest seal has a seal coming tomorrow, but in the meantime, I used two 5/16 inside diameter o rings, but sanded down the second one on a grinder stuck on the end of a bic pen to reduce it's diameter, and so far it held. All is well; I post for informational use, since the original seal gets brittle and I actually observed a crack in the old orig. seal while using sunlight this afternoon.....

Thanks for the info, mine has a slight leak since replacing the speedo cable. Thats an easy enough fix for me!
