64 Valiant 440 build
I decided that because of the sticky tires, I am at risk of breaking my torque arm. I’ve seen on other forums that the geometry of these Spohn torque arms is not great. There’s not enough spread between the rear mounting rod eyes, which causes the adjuster to bend and the top tube to snap. I’ve decided make my own, starting with rebuilding the mounting bracket.
