C30 Rear Springs
 

Anyone know if there are any replacements available or if springs off another truck will fit a 1966 C30? I broke a leaf and would like to just replace the entire set if I can find new or updated ones.

You could retrofit the springs from a newer C30 say a '73+, but you would have to also change the spring hangers. It depends on whether you have more time or money. And whether you feel the need for brand new springs.

At $429 per side, I will keep my eye out for a 73 up truck to steal them from...
