I have a 99-00 Eaton. It is Stage IV port from Stiegemeier. Bought it from a guy local. Was not aware that there is a difference between 99-00 and 01+ Eatons as far as bolt pattern. That is the only reason I am selling it. Spins fine, no problems except it is missing the S/C oil plug. It is also dirty as you will see in the photos. Also in the photos are the etching of Stiegemeier and I believe to be the serial number. After actually looking at the photos I took of it I see it is missing 2 bolts for the snout. I am looking to get $325 plus half the shipping or feel free to message an offer as well. I would really like to get rid of this soon.
