Does anyone have a '68 Ranchero out there have an access panel in the bed of the car. My 68 has a panel screwed in to the bed that is about 2 foot by 4foot. I'm assuming it is a seat well from the Fairlane chassis. I cant get the panel out (bolts are rusted and I can't get them out...yet). What is under the panel? Is there a storage area or is it just opening to the street?
