I have two sets of PRP seats for sale: 2 "Teen" seats (PRP states ages 5-12 - link for dimensions below) 2 "Preemie" seats (PRP states ages 1-4 - link for dimensions below) 4 five-point SFI 16.1 PRP harnesses (2" wide) None of this equipment has ever been installed our used outside of my kids pretending they were fighter pilots in the living room . I am selling because I finally faced reality, bought an 80 series, and sold the Jeep project these seats were going into. I think these seats would be all day comfortable for kids while keeping them in 5 point harnesses. You can see the specs on these seats here (scroll to bottom of page): http://www.prpseats.com/suspension-seats.html These can be bolted directly into a cage or PRP has floor mounts. I do not have weld on cage tabs, but those are readily sourced. The seats run $199 each new, and 2" width 16.1 SFI harnesses are typically around $100 each. I am selling each set of seats for $250 plus shipping. Harnesses are $125 for a set of two plus shipping. Shipping is Fedex ground from 80919. I take Paypal. I will sell the seat sets separately, but will not break up a set. I will sell the harnesses separately in sets of two. The harnesses are adjustable to adult size. A set of seats plus harnesses goes for $350 plus shipping. $675 takes the entire package, including 12 3" washers and nuts/bolts that PRP sent with the seats (I guess for floor mounting the harnesses). First pic is toddler seats Second pic is teen seats 3rd pic is side view that shows 5 point slot and seat mounting tabs PM with questions or post 'em here.
