I am very much hoping that someone here has an older 283 Release and can help me with a measurement. I have contacted GW directly and 4 or 5 dealers, none of which seem to be able to help with what I believe is a simple question --- I am looking for the measurement (or the cushion if you have one) for the aft fold down seat. The previous owner removed the cushion and did not keep it and I need to find one, or at least something similar -- can any 283 Release owner provide me with the measurements for this bolster? It would be greatly appreciated.
