That wasn't the 'exact' design im going to get but it was the closest I could find on google in 3mins at the time.
My exhaust mechanic does the cages, he has a normal pipe bender but for those b-pillar bends he uses a mechanics machine up the road from him, the rest he can do on his pipe bender. Not sure on costs yet because I haven't even got my panel damage repaired yet (even though I have half of it in primer )
