This is the reply I got from the shop when I asked them about it
in other words, they aren't experienced enough to not destroy the ball joints let alone understand the concept of how the C's function :doh:
Every C I've seen bent over the last 30+ years has always been the top, this also includes muscle cars when we'd put wide tires on them because they were chick magnets and looked cool lol.
I had my C's welded on at my local muffler shop, they protected the ball joints, pre-painted the gussets with weldable primer to keep them from rusting before welding them on and painted them black when they were done :thumb:
