I've been using my bed w/ no liner for the last 3 yrs. Cardboard & exercise mats. It's ok untin I get a 1/2 ton of grain on a pallet & they use the tow motor to push it the rest of the way in. I did think I struck gold the other day, one was for sale by the owner in front of his grain store. After taking some measurements seemed like it would fit. I would have tossed it in but my grain was already loaded. To complicate things, I have a fiberglass topper. After 3 trips, no one was around to help me w my shell. After talking w/ Michael on the phone the other day, he expained how the beds were changed w each generation. Thank you for that but i wish I new that before. My 76 Dodge was perfect w any 8ft topper on it but w/ the gen 2's the bed is 2 in closer in the back. I'll have to look around in some salvage yards for the correct gen 2 liner. Dave

Just measure the the bed rim at the front and at the rear ofthe bed and you'll see its not the same...

Thanks Michael, can tell by the way my topper fits from a Fjord of the same year. Ahh nutz!
