Jonny, I won't attempt to tell you how but someone should be along later and give you some guidance. There is a refacing kit available for all the gauges for probably 15 bucks and you can do it.
Note: Checking prices you can see its expensive in most cases to get them rebuilt. I ordered the new small gauges from the Truck Shop in Ca. for much less than a rebuild and have been running them for a couple years with no problems.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
