I’m under my 66C10 putting new spring clamps on the coil springs and I was wondering if I could just change the rear springs out and have a C20 . What would I need to do to change it from ½ to ¾ ton.? Has this been done before?... I want to put a camper on it and do some camping in the Summer so having greater load capacity would really be wonderful.

Any help answering this would be great!
