harold 46- my transmission looks similiar to that but not the same.
i went to napa today and the guy couldnt find any seal that size at all he said, he found my rear axle seals (although they are slightly different he said its the right one)
looked online when i got home by size and found an SKF seal in the same size, number 17645. it was a 1.75 inch shaft and 2 7/8 bore seal, hopefully it works!
