The 1963 Plymouth Fury is a solid full-size Mopar with robust drivetrains, but suffers from era-typical rust issues, outdated electrical systems, and aging rubber/seals after 60+ years. Most mechanical problems are straightforward fixes if you're comfortable with carbureted, points-ignition systems.
Timing Chain Wear and Slop (318/361/383 V8s)
Common · medium severityTypical onset: 80,000-120,000 mi or 60+ years of age
Symptoms: Rattling noise on cold starts that subsides when warm, Erratic idle or hesitation under acceleration, Difficulty starting, backfiring through carburetor, Timing marks won't align during tune-up attempts
Fix: Replace timing chain, gears, and tensioner. Requires pulling radiator, harmonic balancer, timing cover. Shop time 6-8 hours including gasket cleanup and re-timing. Original-style single-row chains wear faster; double-row kits recommended.
Estimated cost: $650-1,200
Floor Pan and Trunk Floor Rust-Through
Common · high severitySymptoms: Visible holes or soft spots in driver/passenger floor, Trunk holds water after rain, Exhaust fumes entering cabin, Rear spring mounts showing surface rust or flaking
Fix: Structural rust repair requires cutting out rot, welding in replacement panels. Floor pans run 12-18 hours labor for both sides; trunk floor another 8-12 hours. Rear frame rail inspection critical—if compromised, costs skyrocket. Many owners patch with fiberglass temporarily, but proper fix is welded steel.
Estimated cost: $2,800-6,500
Push-Button TorqueFlite Transmission Cable Binding
Occasional · medium severitySymptoms: Push buttons stick or won't release, Transmission won't shift into selected gear, Buttons feel crunchy or require excessive force, Intermittent neutral safety switch issues
Fix: Cable assembly from dash to transmission corrodes internally or cable housing splits. Replacement cables are reproduction parts requiring dashboard partial disassembly and linkage adjustment under car. 4-6 hours labor. Some shops unfamiliar with push-button system may struggle with adjustment procedure.
Estimated cost: $550-950
Generator (Not Alternator) Failure and Voltage Regulator Issues
Common · medium severitySymptoms: Ammeter shows discharge at idle, Dim headlights, weak horn, Battery repeatedly goes dead overnight, Burning smell from generator, hot voltage regulator
Fix: Factory generators are 60 years old; brushes wear, bearings fail, or armature shorts. Rebuilt generators run $150-250 plus 2-3 hours labor. Voltage regulators ($40-80) often culprit before generator itself. Many owners convert to alternator ($300-600 all-in) for reliability, requires bracket and wiring modifications.
Estimated cost: $280-850
Carburetor Flooding and Accelerator Pump Failures
Common · low severitySymptoms: Raw fuel smell, black smoke on startup, Engine floods and stalls when hot, Hesitation or flat spot on acceleration, Fuel leaking from carburetor base or bowl
Fix: Carter or Holley carbs used in '63 have dried-out gaskets, stuck needle valves, or failed accelerator pump diaphragms. Complete rebuild kit with proper float adjustment takes 3-4 hours if you're methodical. Alternatively, replacement remanufactured carb is plug-and-play in 1.5 hours but costs more.
Estimated cost: $220-650
Brake Master Cylinder Leakage and Single-Circuit Failure
Occasional · high severitySymptoms: Brake pedal sinks to floor under steady pressure, Fluid dripping at firewall, inside under dash, Spongy pedal feel even after bleeding, Complete brake loss (single-circuit system—no redundancy)
Fix: Single-circuit master cylinders leak internally or externally. Replacement is straightforward—2 hours including bench bleeding and system bleed. CRITICAL: This is a single-circuit system; total brake failure possible. Many owners upgrade to dual-circuit master from later Mopar for safety, adds fabrication time.
Estimated cost: $180-450
Front Torsion Bar Anchor Corrosion and Lower Control Arm Bushing Failure
Occasional · medium severityTypical onset: 90,000+ mi or rust-belt cars
Symptoms: Clunking over bumps, loose steering feel, Uneven tire wear, car pulls to one side, Front end sags on one side, Visible rust at torsion bar hex socket in K-member
Fix: Torsion bar anchors rust in K-member, causing wandering ride height. Lower control arm bushings dry-rot and crack. Requires front suspension teardown, 8-12 hours labor. If K-member is structurally compromised by rust, repair becomes major undertaking. Bushings alone are 6-8 hours with press work.
Estimated cost: $950-2,200
Buy one if rust-free and you're handy with old-school carbs and points—mechanically simple and parts available, but corrosion is the real killer on these full-size Mopars.
