[Closed] Bossnut suspension spares

Hi,

I've recently bought a used Calibre Bossnut on Gumtree (uh oh) and whilst it looks like it's been well care for and upgraded there's significant play around the rear linkages/suspension and many of the bolts are rounded off probably in an attempt to sort the issue.

My question is, does anyone know where I can get a full bearing/bush set as well as the bolts to try and sort the problem properly? Are these common sizes or unique to these bikes? It's a Rockshox Monarch R rear shock. This is my first full-suss bike so unsure which way to proceed.

Thanks,

Iain
