Since the oem seals are on the high side of ridiculous in terms of pricing I've been researching some alternatives.
For the 18 spine output shaft seal it looks like SKF 9710 will work.
For the driver side axle seal it looks like National 710318 crosses over.
For the passenger side axle seal it looks like National 710353 crosses over. You can even see the factory part # on the picture here: http://www.ebay.com/itm/NATIONAL-710...6f1e6c&vxp=mtr
Anyone have any experience with these? I have the output shaft seal in hand and it appears that it will fit in the transmission case, but I won't know for sure for a couple days. I'm resealing the trans while I swap out some syncros to prevent leaks.
so, to summarize SKF 9710 should work for the 18 spline output shaft, national 710318 should work for the driver side axle seal, and National 710353 should work for the passenger side.
SKF 10923 looks right for the 25 spline output shaft seal:

MUCH cheaper than oem.
I have confirmed the 18 spline outputshaft seal and the 2 axle seals fit fine. I do not have the ability to try the 25 spline output shaft seal.
