The Wilwood Forged Dynalite-M front kit (MPN 140-13476) is a complete front disc conversion for 1965–1969 Ford Mustangs, built around an FDL-M four-piston forged aluminum caliper and an 11.30-inch one-piece rotor. Wilwood's Classic Series front disc brake kits for 1965 to 1969 Ford Mustangs offer disc brake upgrade solutions for OEM drum or disc spindles. The manufacturer also describes its bolt-on kits as designed to provide superior braking performance, which is the real reason to pay more than stock drums or a budget conversion. Searchers looking for a 1965 Mustang drum-to-disc upgrade, a Forged Dynalite front kit, or a Dynalite-M Mustang brake conversion will find the specs they need below.
Fitment is the step to verify first. Kit may fit some 14" wheels. The manufacturer asks buyers to check the wheel clearance diagram in kit installation instructions before purchase. The install sheet confirms the design works on both drum and disc spindle configurations, but disc-spindle cars need a closer look, because on some models of disc brake spindles there are "ears" where the OEM calipers were mounted and these "ears" interfere with the assembly.
Plan on a bolt-in job with some drilling. The manufacturer's assembly sheet has you use the caliper mounting bracket as a template and drill a .332" diameter hole, so mark and check alignment before drilling. The same sheet calls for Wilwood EXP 600 Plus Racing Brake Fluid and an in-line two pound residual pressure valve, and it says to test the brake pedal before driving.

Per the manufacturer's assembly sheet, use the caliper bracket as a drilling template and drill a .332" hole, then check the ear clearance on disc-spindle cars before you assemble anything. Install the in-line two-pound residual pressure valve, bleed with EXP 600 Plus, and test the pedal before driving. Confirm with the manufacturer whether flex lines ship with your kit, since sources vary on that point.
