1976 12hp auto rear axel oil seals

[mowboy 11]

I cannot believe I can't locate this on my own, stubborn I guess. But I need help- I'm looking for  the rear axel oil seals for what I believe I have (no id tag). That is a 1973 12 hp Auto (1-0465) with 90-1136 Sunstrand hydro.. I thought )and ordered the SKF 11124 (wh # 6449). But went and pulled the old seal out today and it's almost 1/2" wide, so now I think the 11124 is wrong.

Any help is appreciated.

Thanks -but what I read shows what looks like the oil seal with diagram #4-20, however in the  list it does not list  4-20. am I missing something here? I'm positive the hydro is #90-1136 and assumed the  transmission was 5089

looks like you need number #4-16 seals

6449 1 1/8 axle

100607 1 inch axle

looks like the OEM seals are pretty thick. I take it the old seals were thinner when you removed them?

the new seals are thinner but work.11124  You could always double them if you wanted.  Modern seals are routinely thinner than older ones..
