Spectrum fix whammy bar nut

Can someone please direct me to a replacement nut to hold my whammy bar in place??
It’s a spectrum fix. Thanks.

Have a look at this tutorial on our website: collar Insert replacement

Yep… it’s a good fix; I’ve done it on two of mine!

I’ve also got a couple of those collars in my spares box, but not quite prepared to let ‘em go yet as you never know what may pop up up on the auction sites!!
