Fork Brace

This one was originally designed and built by race tuner Pierre des Roches, and sold in volume by a California company, Racecrafters. It was originally called the "Golden Gate Bridge". It would need either bending to fit and not side load the sliders, ot shimming to not pull the tubes together.

K&L, Tucker-Rocky used to have a nicer one made from cast aluminum, bolted together, 5 pieces. It was made in Japan.
