[TR] tr-3 diff. oil seal or speedi sleeve or both?

[Gary Nafziger]

I continually get diff leaks (newly restored tr-3)B  always dripping from the
bottom of cover, however I've taken the cover off, cleaned up the mating
service to fit nicely against the diff and also put on a thicker gasket.B 
Made sure the overflow tube is open.B  Still leaking.B  Next step is pinion
area.B  I'm thinking it's leaking there and blowing back to bottom of diff
then dripping off.B  Make sense?B  Any other opinions?
Winter project will be dropping drive shaft at diff, removing oil seal and
installing oil seal and possibley speedi sleeve.B  What recommended?B  Only
speedi seal?B  only oil seal?B  or both?B 

Also I have a hell of a time finding TRF parts through the "search" click.B 
put in pinion, diff, speedi seal whatever.......usually hopeless.B  Moss is so
much easierB  but I love TRF and they're seemingly "homier" atmosphere.gary
