Hi folks....new to the Forum and Happy New Year to all.

I recently purchased a 1977 F350 Camper Special (140" WB). According to my owner's manual, these F350 Camper Special's came in 1 of 3 GVWR configurations: 8300, 8900, and 9900GVWR. Taking the tires out of the equation, and all things being equal, ie, frame, axles, brakes, etc, the only thing left is different spring packages. I'd sure like to know where to find the info, and what they where.

Anyone got some ideas or suggestion?

Thanks
