The 8609 seal which is the bigger one that goes in the housing is old part number 2466-842 and the new Mopar number is 1-04505098.

The smaller seal that goes in between the two levers is old part number 2466-548 and right now I can't find the new number.

You can always just get the parts guy to look up a 98 or so Dodge pickup with a Cummins and auto and they will be the same.
