Bar End Expander

Has anyone got, or does anyone know where i can find the expander that sits next the bar end itself (not the expander further up inside the bar). I have the part no. from the fiche but it won't register on my dealers computer. Doesn't need to be a genuine part, I'm sure there must be places that sell these kind of fasteners at a reasonable price.
While i'm whinging about Suzuki's prices, how does £50 sound for 5 replacement stickers (2 x 'sv650s' front fairing, 2 x tank badges, 1 x 'suzuki' front fairing).

I used a decent sized rawl bolt with a locknut araldited onto the end. Much more secure than I could ever get the original ones.
