Chuckie Strut Tower Brace.

Some miss information there, Chuck Pierce's design uses stock Audi S4
tower plates and mounts up with the stock 200 Brake reservoir. The rest
of the parts are source from industrial standard supply and are over
designed for the application. The cross bar is not a box tube but a
round steel tube with fairly thick walls. The adjustment bolt with
reverse threads on opposite ends is standard hardware issue (just need
to know which hardware story to go to) and treaded into the tube with
lock nuts on each end (look at a Nissan 350Z for the inspiration).
I used the Chuck Cross bar to push out a collapsing right shock tower to
get it back to factory specs. If you can find one or can talk Chuck
into making some more, you will find it works very, very well.
