the bolt runs all the way from the back of the subframe through the coupler and toe arm. in the pic one bolt is longer than the other because its all i could find at the moment.
the old hicas rack and my eliminator bolt up differently.. my setup uses the hole intended for the NA toe arms that for some reason appears on twinturbo models. i will incorporate the old hicas parts and the old rack bolt hole for a more sturdy system in the future.
