try this....
If you have the drop down from the forward bulkhead table...On the forward side of your nav table you should have a small cushion (#1) app. 12"h x 18"w (Part K 40 22 25 390)snapped onto the side wall of the nav station, on the aft side of your nav table, snapped on the hull wall, you should have a larger cushion (#2) 18"w x 48"l (Part K40 22 31 390) and finally on the side wall of the aft cabin (under the cockpit area) you have have a last cushion (#3) app 10"w x 60" l. (Part K40 22 33 390) They are all the same thickness.Once your table is down the narrow (#3) long one can go on the table lenght wise on the Starboard side of the table, than in the hole left in the middle you combine both cushions found near your nav table (#1 and #2). Voila.Hope you find all of your cushion and this works out.Don't you love a good puzzle!G
