1963–1976 C2–C3 Corvette Radio Control Shaft Mounting Nuts Pair 1225217 - OEM Number(s) (1225217,7279805)
Secure your C2 or C3 Corvette radio control shafts correctly at the dash or console bezel with this reproduction mounting nut pair built to original specifications.
The radio control shaft mounting nuts on a C2 or C3 Corvette are the small but essential hardware pieces that lock the radio control shafts securely where they pass through the dash or console bezel. Over time original nuts corrode, strip, or go missing during radio service — leaving shafts loose and the bezel unsupported. Correct thread and correct thickness matter here for a secure, rattle-free fit.
This reproduction mounting nut pair is zinc plated for corrosion resistance and sized correctly at 7/16 inch — 28 thread with 1/8 inch thickness for correct fitment at the radio control shaft location on 1963–1976 Corvettes. Sold as a pair — two nuts included for complete installation.

1963–1967 C2 Corvette. 1968–1976 C3 Corvette.

Because Details Matter:
