Found some lift springs and upper control arms for 1963-1987 C20 and C30 here

Anyone ever order custom springs? Since there is so little aftermarket support for these trucks, other than stock replacements if you’re lucky. I would imagine with a little knowledge someone could have a specialty shop make some spring pretty easy, trouble is I’m missing that knowledge.😅
