The American Professional II Stratocaster is Fender's core USA workhorse, refined but not radically different from a standard modern Strat, a deep C neck and V-Mod II pickups are the main upgrades over a Player series guitar. It uses the same modern 2-point synchronized tremolo footprint found across most current Fender Strats, so standard aftermarket 2-point trem parts are a safe bet.

Not published by Fender: tuner hole size and bridge mounting spacing. Measure these before buying tuners or a bridge.
Tuner peghole diameter is cited at 10.26mm in owner/forum sources, not a published Fender spec sheet figure, so treat the exact size as close-but-not-manufacturer-confirmed.

Matches this guitar's modern 2-point tremolo spacing.
Modern 2-point tremolo at the standard 52.4mm American series spacing, matching this bridge's modern spec.
Built for exactly this tier of Fender Stratocaster, matching the modern 2-point spacing closely.
This bridge is built specifically for modern American Standard/Professional-tier 2-point Strats at 52.5mm, essentially the same modern spacing as this guitar's 52.4mm bridge. The manufacturer explicitly states it is not intended for Squier guitars.

View at ReverbThis bridge mounts on the same posts as your stock bridge, but its string spacing is wider than stock. Gotoh's narrower NS510 model matches your stock spacing more closely, but this wider version should still physically fit if you don't mind the difference.
This is Gotoh's standard 510 tremolo, built to 54mm string spacing, wider than this guitar's modern 52.4mm spacing. Gotoh's standard and NS510 (Narrow Spacing) tremolos share the same post mounting spacing, so this should physically bolt onto this guitar's existing studs, but the wider string spread means strings will sit further from the neck edge than stock. Revised from an earlier Not compatible verdict, this bridge likely does mount, it just changes string spacing from stock rather than failing to fit at all. Gotoh's NS510 narrow-spacing model is the closer match to stock spacing.

This bridge mounts on the same posts as your stock bridge, but its string spacing is wider than stock. Your strings will sit a bit further out than you're used to, worth trying before committing if that matters to your playing feel.
This bridge's real spec is 54mm string spread (confirmed via Gotoh's own product page), wider than this guitar's modern 52.4mm spacing. Gotoh/Wilkinson's narrow and wide 2-point tremolos share the same post mounting spacing, so this should physically bolt onto this guitar's existing studs, but the wider string spread means strings will sit further from the neck edge than stock, worth confirming feel and fretboard-edge clearance before buying rather than assuming an exact match.

View at AmazonThe saddles fit your existing bridge, but the piezo pickup system needs a preamp and battery, which usually means a new cavity has to be routed in the back of the guitar.
The saddles themselves fit the standard tremolo block, but the piezo system needs an onboard preamp and battery, which typically means routing a new cavity in the back of the guitar unless one is already present. Not a drop-in electronics swap.

These should fit, this guitar's tuner holes are reported very close to standard, but the exact hole size has not been independently confirmed, so a snug fit is possible.
One forum source cites the American Professional II's peghead holes at 10.26mm, slightly larger than the 10mm bore confirmed on the Player series. Not a manufacturer spec sheet figure, so treat the exact size as unconfirmed even though the tuner family is the same.

View at AmazonShould fit closely, but this guitar's exact hole size has not been independently confirmed. Worth measuring first.
Sperzel's standard line uses a 10mm bore, but this guitar's exact hole diameter is only cited at roughly 10.26mm in a single forum source, not manufacturer-confirmed.
