I dropped my '66 with 2.5" spindles and 3" springs up front with a stock length shock. The crossmember would bottom out before the shocks did. I relocated the upper mount by using a modified Currie rear axle shock mount.
On the rear I used another pair of stock length front shocks, and used the new studs that come with the shock to mount them outboard of the frame rails. The lower shock mount brackets were flipped side to side and one new hole was drilled in each for the U-bolt to pass through.
Frizzle Fry came up with the idea, I just copied it. Works better than the reloaction kits since the shocks go outside the frame where they have more leverage on the axle. The truck drove great and was very stable, even at illegal speeds on the interstate. Even with stiffer gas shocks it rode better than my dad's all-stock '66 C10, mostly due to the better body control from the sway bars and better suspension damping.
