I am trying to order the lip seal for my 1450 again I ruined the 1st one. I can not come up with a matching part number. Tractor s/n656585. Seal # 4 in the diagram which is 394847 r91. And a picture of the 1st ones box. Can someone please help me get the right seal number to order from cc specialties. Thank you. And yes I know he is gone for a bit.
