Lowering a C-20

[v_dub_ya]

I have a '77 C-20 and i am lookin at lowering it a bit, 3 inches in the front and 4 inches in the back.  I havent had that much luck finding lowering components for this application.  There is all kinds of stuff for the C-10 and C-30, but not too much for the C-20.  Anyone have any good places to look, hopefully not where ive already been?

Thanks for any help

If you don't plan to use it as a 3/4T truck you can swap the upper/lower control arms to the 1/2T and use C10 components.  This is what a lot of people do.

If not, you need a 3" drop spring and a hanger/shackle kit.
