FF: Forks Brampton Coil Over Shocks

Alyn, after reviewing all options I see why you are taking this course--you will have the best option for Bramption's. Count me in for 1. What are you running on the back?
I have a rebuilt standard Vincent unit on the rear end.
I have a model b rapide and am interested in the coilover. I note the length looks about 300 mill from the base of the top thread to clevis hole. I have jacked up the bike( wheel off ground) and it measures about 270 mill from under the top mounting to the top of the bottom yoke/ cross member. I can't measure to the headlamp lug because a previous owner chopped it off! I would therefore have to make up a lug and weld it on assuming the material is suitable for welding. It just seems a tad long.

I hope the above doesnt mean you are relying on the headlamp lug position as your only bottom security. On my USA unit (which I have displayed on here recently) it only serves to reinforce and secure the plates that hold the unit on the original spring anchor projection.
After twenty years of riding on many types of road it has been wonderful.
All I can say is it has been used for over twenty years and no problems. I think Robert Watson incorporated the extra lower "security" to satisfy the manufacturer. I cannot comment except that after twenty years of crappy Australian roads, dirt, gravel, pot holed and highway; nothing has broken. I guess you could weld a plate inside the lower link if you were that concerned., however I would want an expert welder to do that job. Remember, the spring is only 130lb.

I would be hesitant to do any welding unless you are an expert. Buy a new link for safety.
I agree I don't think I would be happy to rely on just the lug as it was not designed for that purpose, even though it may be well up to the job.
What I really want to know is what is the link/crosspiece/yoke or what ever its called is made of and is it suitable for electric arc welding does anyone know this?
