Maybe so in non-covid times but might not be worth it at the moment. I priced some oillite round stock a couple months back and it would have been cheaper for me to make the bushing out of gold. I know you can get the bushings on Amazon, a full set is like $60. If you need them tomorrow though, you might have to find them locally.If you’re think of change a bunch, find some material and take a sample to a machinist. Way cheaper. Local makes a few bucks and you’ll save some.
Years ago I changed them all on my old powder special. Would have been 10X more buying them.
