I lost the split collar off RDM wave grenade extension. Do these get sold as spare parts anywhere?
Extension is pretty useless without it unless there are some simple hacks? (i did think about cutting some short sleeves off an old mast).
Cheers,

I Imagine you can order thru Revolution Boardsports?

If not, stainless pin (or bolt) and a collar from another extension will work,. If all else fails, bolt thru and a collar made with a bit of mast bottom say 1cm with a bit of a groove for bolt to sit in.
