i dont know about the bilstein shocks, but i know with stock oil shocks there is a rubber bushing up inside the bell of the shock that can be cut down by drilling out the spot welds and taking the bell off, and voila more shock travel... but again i dont know what the inside of a bilstein looks like, otherwise you can buy a shock for lowered front ends, but its only made for the lowest of lows, even my brothers old 74 with about 2\" off the ground the lowered shocks were too short.
