I could check measurements on 1935 36 and 38, if you want to try an ID it. In the meantime you may like to state the year of your G3, so some one could measure their's for you. Perhaps your bike is not a G3? prewar G3 had mag at the back. I'm sure post war G3 was coil. Maybe you have a G3L G3LS or another G3 model type.
Hi Rob,
Thanks for the information. I am pretty sure that you are correct that it is an AJS part because, as you say, the AJS had the mag at the front.
My bike is a bitsa, the chassis is 1958 G3LS so when I come to get a dating certificate and V5 that will be what will be written on it. However I am using an earlier engine (because thats what I have) which doesnt have the extended crank axle for the altenator so I will be using a magneto. I therefore have a choice of where to mount it, front or back. I have decided on a front mounting hence my question.
I picked the mag platform up with a few other parts but now that I know that its a pre-war one I know that I dont need it and I wont be modifying it.
