I am still unsure how the factory fitted the rubbers to the oil tank originally?
I am happy with the way I now use thanks to your replies but, why are the frame holes not just 5/16" rather than just under 3/8"? sloppy fit but I have checked 3 other bikes and they are all the same, but this gives very little purchase for the spacers to clamp up to, and why is my oil tank top hole too small for a distance piece to fit through being just over 5/16? I have just opened it out to slide the distance piece through but how was it done when it left the factory?
Tool box, I have fitted the rubbers into the depressed washers fitted to the large top mounting. but why is the top rubber mounted? if it flexes on the rubber mounts then the two solid fixings on the inside of the toolbox will also flex, fretting the toolbox metal?
I know thanks to you I have an effective mounting but I don't believe BSA were incompetent so what am I missing?
Thanks, Dave.
