I bought this but never got around to installing it so it has been stored for a bit. The belt is additional to what they want for the kit, which together goes for around $270, however if you act now I can sell you this for the one time low price of $150. Shipping would be extra and I suspect around ~$25-$28. I do take PayPal
Eximorís blurb about this seat:
REAR JUMP SEAT - NAS 90 CAR DENIM VINYL Model #:EX9607NAS
Denim vinyl front with black vinyl sides and back. Includes mounting brackets and* strap for securing in folded away position.
Rear inward facing seats, allows you to fold the base towards the back rest and neatly stow away when not in use. With the seat base folded the floor / load area is totally clear so it will not inhibit the boot space.
Includes mounting brackets and strap for securing in folded away position.
Also included is the retractable lap belt with the hardware (missing one of the bushings)
