Identify the bridge that is actually installed
Use the bridge model or part number where available, plus clear photographs of the plate and block. The guitar model is helpful context, but a previous owner may have replaced the bridge. A two-point or six-screw description does not specify the block’s own attachment holes.
The linked Gotoh 510 FE/BS block lists particular 510-series models and explicitly excludes Gotoh 510 bridges with 52.5 mm width. Do not extend that compatibility to every Gotoh bridge, Strat or Squier.
Measure the block and the space around it
Use the same measurement points as the product drawing. Ask for any missing dimension before taking the bridge apart or placing an order.
Block height, width and thickness, including any stepped or projecting sections.
Block-to-plate screw centres, thread specification and string-hole positions.
Tremolo arm location and connection type; for a threaded arm, confirm diameter and pitch.
Spring attachment points and clearance inside the cavity through the intended tremolo movement.
Clearance to the rear cover with the bridge at its intended resting position.
Keep mounting spacing separate from string spacing
The linked Vintage/Narrow complete bridge set lists 2-7/32 inch mounting spacing and 2-1/16 inch string spacing. These are different measurements on the same assembly. A matching string spread does not confirm that the mounting screws line up.
Likewise, the height options on the Gotoh block do not certify cavity clearance. Compare the selected option and its drawing with the installed hardware.
Confirm the contents and plan the setup
Check the selected product’s inclusion list for the arm, screws, springs or claw you need. A complete bridge set and a replacement block are different purchases; do not assume accessories or printed instructions are included with every block.
After fitting, check the spring balance, bridge resting position, action and intonation. Brass construction alone does not establish better tuning return or a guaranteed sustain increase.
Frequently asked questions
Can I choose a block height from the guitar brand alone?
No. Identify the installed bridge, compare its attachment dimensions and measure cavity clearance. Brand, country of manufacture and body style are not complete fitment specifications.
Are M6 and 10-32 tremolo arm threads interchangeable?
Treat them as different thread specifications. Confirm the arm connection for the selected block and never force a threaded arm that does not turn freely.
