I have a Rear oil seal that I bought for my 5.0 EB auto trans a long time ago and never fit it. Part no: 402965N
I want to replace the rear Oil seal in my EF 5 speed Manual trans and was wandering if it is the same part. I googled without any luck. If anybody on here knows this part and can give me any info I would greatly appreciate it. I figured it should be as the prop shaft teeth are all the same size in the E-series.

Yep, same...fits straight in.
But, it would be better to fit a BA 4sp auto rear seal...they have 4 lips.
