I got this damper from EBay. It has a 75 mm stroke. I have prototyped a bracket in 3mm aluminium as shown but because it was made with hand tools, I simplified it to the sketch shown. The real bracket will be made in 10mm billet alumium.
The difference in shape and dimensions between this and Vincent's is because it is to fit the modified steering stem and the body pivot puts the damper further towards the front of the bike. With this set up, there is about 20 mm of travel left lock to lock and this can be equalised by adjusting the damper body in its clamp. I prototyped this on the bike without the forks but with the lower link (With sealed bearings) but I'm pretty confident that it won't foul the spring boxes. The main bracket will be spaced down with a modified 6 mm thick version of timetravellers three hole bracket without the damper rod pivot hole. This is so that there is clearance for the near side eccentric from the 10mm bracket and to provide a flat bearing surface on the underside of the new steering stemThanks to Greg and Vincent for their help.

Thanks Vincent and the others who have sent in diagrams. I am away from home for another couple of days and hope that when I get back the Hyperpro copy will have arrived. I already have a cardboard mock up something like those illustrated but need the actual damper to get the heights correct. I have a question which I thought I would pose later. When I have these damper links made, and the aluminium lower motion blocks for the new steering heads would people like me to get them black anodized or would you prefer to paint them yourselves later?

Its not just the colour. Would people like them anodised? The colour is a different matter. I have seen both red and blue Vins and even a white or cream coloured one, so each to his own.
