71 K-10 Axel Replacement Question ?

[54blackhornet]

Hope you all had a good Thanksgiving, I picked up my first 4x4 this summer, ripped the sheet metal off over the weekend to see what I have to work with. Both axels front and rear need to be replaced as well as the leaf springs. I plan on tearing the frame down to sand blast and repaint and start fresh. What do you guys suggest I look for, as far as a downer vehicle to replace the springs and axels ? Can you mount 3/4 ton springs and axels on a 1/2 ton K-10 frame ? Thanks in advance for any suggestions you guys can offer.....
