Hello. Are you anywhere near Paisley? If so there's a hardware shop round the back of Halfords I've used many a time, I can't forget the name but it's maybe on Abercorn St?
I've got a couple of jate rings to it to my Rangie so I'll be needing bolts too, that would be my first call.

To add to my previous post, it's Robert Livingstone Engineering on Abercorn St. Helpful and cheap as chips.
Mod feel free to merge my two posts, ta!
