Brian The Mulfab and librands syatems are one in the same. There was an article on them in the October(I think) issue of Miscellany. My Roadster is currently with Russell Paterson having the system fitted along with AVO rear shocks and a panhard rod. Expectation is a transformed suspension. I took the plunge based on 'informed' advice as unfortunately it was not practicle to attempt a test drive of a converted car. I am told components are currently being fabricated and the stub axles are away being modified, plan is the car will be ready for the spring (whenever that turns out to be in scotland). If Russell takes some photos during the work I will post them
