Many thanks for the superb info. I will investigate further.

Thanks for the replies, it sounds more difficult than I thought as finding the correct fittings is taking some doing.

So I am about to buy a Steib TR500 sidecar, I know very little about sidecars, other than they are an acquired taste. One thing that I need advice on is, how will it fit to my 1947 Square four with a rigid rear end. Does anyone know what fittings are required.

Running a Wassell Evolution 30mm on a Matchless 500cc G80 CS, runs very well.

Theres very little on Sq4s on youtube that isnt years old. Its about time us owners did some new content. If only I could figure out how to do it.

Merry Christmas to all.

Thanks Gents I shall pass on the info.

No, that is the earlier one. Drags list them for the 54-58 but currently on back order. He`s looking for another source of supply. But thankyou for looking.

Hello, I have a mate that is after a brush plate for his dynamo its a C35SD 1954-1958 and its on his Square four. Does anyone have one or know where he could buy one from.
Many thanks
Colin
