You could call Addco on both the rate and the design of the C10 bar to see if it works OK with a lowered truck. I looked it up in the Addco catalog as the picture looked like a leaf spring bar for a top mount spring. They do a good job of matching there bars in sets front and rear. For what you are trying to do it would be a good option to get the pair. Also if you put a long panhard bar on the truck it really helps the roll center and made a big improvement in the handling on my 66.
