Ones I’ve used and can recommend:
Gear are great, Joe is a top dude (Hi if you’re reading Joe) and the guys are always helpful. (He once let me rummage for about half an hour downstairs in the workshop in a huge box of mech hangers unsupervised- uncommon these days.) They’ll do your forks no probs, I think.
Willy Bain is also highly recommended. Nice bloke. Knows his stuff. Worth a call.
Cyclesmith in Rutherglen. Smudger can do just about anything, but might send forks off.
Surprised no-one has mentioned Billy Bilsland.
Lastly, don’t discount Alpine. Always helpful.
