Presumably you will acquire one of those metal bases from R&R. So I've concentrated on the rare rubber part. As a stop gap until one turns up, one could be turned in hardwood or aluminium and painted black. The measurements are near enough for a repro. The five grooves are about 1/8" deep Ron
As far as I know, the B set antena's are the same with the exception of the ring brush guard fitted to those in a more vunarable positon. I'm getting ready for a weekend away, but I'll try and take some pictures/measurments tomorrow. Ron
I'm sure that Triumph would have returned unissued brand new WD bikes to the factory for a civilian make over. But I've never heard that they restored old used examples as did RE?? Ron
Yes I forgot about the pump. That means cut and re-weld the bracket. It looks like the top one is the best you have. I can't remember if Jan makes this chainguard or not? I'll ask him. Ron
Distance L is aprox 5 1/2" on both mine.
However the pump brackets are 15" on my 3SW and 16" on my 5SW. Considering that my 5SW chainguard is about 3/8" longer than my 3SW. I would suspect that this one is a reproduction?
What do your pump brackets measure?
PS have you got a 90 link chain? Maybe your wheel should move backwards a bit more?

I appreciate all the suggestions and advice from you guys. In the 35 years I've owned it, I've never had such a long winded problem. Especially since I worked as a motor mechanic in the 60's & 70's when plugs and points and simple carbs were an every day occurrence. Ron๐
