Me too and my friend Gary Fisher of Totallyalfa.com is currently making me some repair sections (the toothed hinged part - see pic below) for my mechs, out of stainless steel. This should enable the rusted bits to be removed, the backplate wire brushed and repainted / treated and then the new stainless hinged mech to be bolted back on. Fingers crossed this will solve the problem.
If there is enough demand for bits like this, he can make a batch. I’ll keep you all posted.
