Sizing Guide Rail Bushings

[Avery Todd]

List,

Any opinions on the best way to size these new
bushings?

I've heard of using a heated damper wire;

An alcohol/water treatment with bridge pins of the
appropriate size (same as damper wire? slightly
larger?).

Any other methods?

How do you tell for sure they're correct "before"
you reinstall the guide rail?

What about lubrication? Protek?

Rather elementary questions, I know but I just
wanted to get some opinions from others who've
probably done this a lot more than I have.

Thanks.
Avery
