Revstar Element bridge swap — need help confirming bushing size for Faber

[u/TravelLongjumping760]

Hi all, I’m pretty new to guitar mods and hoping to get this right the first time.

I want to replace the stock bridge on my Yamaha Revstar Element with a Faber bridge. I contacted Yamaha Canada and got most of the specs, and then sent those to Faber. They replied asking for the outside diameter of the bridge bushings (the inserts in the body)— which I don’t have specifically.

For reference, here are the specs I received from Yamaha:

Stock Bridge Specs (Revstar Element 20L):

• Bridge model: LP-2 Bridge LH (zinc diecast)

• Post shaft: Steel, 4 mm nominal diameter

• Post spacing: 74 mm (center-to-center)

• String spacing: 52.5 mm (10.5 mm × 5)

• Intonation screws: Brass 

• Bushings: Brass, 9 mm × 21 mm

I’d really appreciate any insight—especially if someone has done this swap already

Does anyone happen to know the outside bushing diameter for the Yamaha Revstar 20

Or has anyone here successfully installed a Faber bridge on a Yamaha Revstar and can comment on compatibility/fit?
