Help!!!!!

Not really a technical question - I'm trying to work out what type/size nut I need for the original indicators on a Daytona 955i as it doesn't seem to be metric. Have tried looking at various parts lists but no joy

 

Are you checking for both fine and coarse metric threads?

Errr no wasn't checking scientifically, just trying a few in the local hardware store. It's a finer pitch than the aftermarket ones currently fitted.....

 

You will maybe need a specialist fastener. If none local to you try

Thanks for all the replies, think I can find what's needed now.....
