The kit offered by ece allows you to use your existing tie rods and other suspension components. It's the best bang for the buck I think. They sell brake kits as well. I have the 4-6 drop on my 65. With the 18" rear wheel it tucks nicely, the front 17" wheel has 1.5" from top of tire to fender, the tire size is 255/45. I don't bottom out and can still turn without eating sidewalls up. The only thing that may be an issue is the header flanges. I have to get into some driveways at an angle. The kit uses the new KYB gas shocks. 2.5 drop spindle and 1.5 spring drops the front. A coil designed to drop 6" does the rear. I've hauled a yard of 3/4" gravel in my truck before and it didn't bottom out.

I can explain it to you, I can't understand it for you.
