Low Reverse Piston outer lip seal part#

[WE287GN]

My fact seal doesnt seam to have a # on it..Doesnt really match the style of what I have in my kit..
The lip of the one that looks like it matches the diameter has a longer lip on it..
Want to be sure..Wondering if anyone knew the correct replacement #..
Something tells me I went through this the last rebiuld I did, but I cant be sure..
Thanks

Finally found it under the kits manf website..Luckily they had a list of the individual seal #'s..
If it were not for that I would have guessed it was the wrong seal, its lip is quite a bit longer than the original..
Came up with OE 8628364 low reverse outer piston seal

thanks
