Ok. Here is the deal. A leaf spring for a K5 is about $400 each. Honest! Now I found a company that can make them custom for me, for much less. Now I need measurements. I know there 52" apart, but for a 4" lift, how deep does it drop when the leaf is just resting on a table (no load). And how thick should the pack be. I need this info for both front and rear leafs. I really really hope anyone can give me these figures. Would be great. 1988 K5 Blazer Silverado Grand GT in the Netherlands.
