MR580530 Pinion Seal is $17.17 + Tax from the dealer Only should take them 3 to 5 days to get it in. Rock auto show's they have one for it for like 5 bucks but it lists the 8" and 9" axles. Nothing specific to the 9.5" axle.

At this point the truck needs to go to adams, we need you to get some of the compressor bracket stuff fixed up so we know where how were gonna run the power and hook up the pressure switch and arb stuff. Can I get it dropped off this week?
