I was going to redo the drivers seat on my SN 2001 but ended up selling the boat (it should work on other models as well. I bought this shell from Christine's for $100 last fall. I would like to get $100 but open to reasonable offers. The plastic is in very good condition without cracks or distortion. The yellow discoloration is from the seat foam which was removed for the seat. Dimensions between the bolt holes is approximately 9" wide x 11" between front and back row If you need any other dimensions let me know.
