The length of the brake rod will be found in the parts book but note that it is not easy to make, being fashioned from a 3/16 dia rod with a 26 tpi thread. The threaded portion is then rolled in order to put two flats on it thus causing the thread to increase to a bastard 7/32 x 26 tpi.

Again a parts book should tell you about the carb spacer but even if not originally fitted they are a good idea. A spacer will not prevent fuel dripping onto the spark producing device, this was done on purpose to ensure that owner's had to buy a new bike every now and then to replace one that had just burnt to a cinder!
