GT TIPS
Fuel System
We recommend installing a new European-made Weber 32/36 carburetor, and protecting against ethanol-fuel issues using our heat shields, air filter and header options. You should also replace fuel tank hardware, including vent tubing.
Parts: 9017, 9004, 9073, 9063, 9066, 10023SS, 9071.
Cooling System
Replace hoses and fan belt, install improved-design water pump and consider radiator upgrade. In warm climates, install lower-temp thermostat.
Parts: 11001, 11002, 11003, 11005-160, 11006, 11023.
Electrical System
Ensure battery is charged, and replace all charging system cables and wires. Clean or replace battery mount tray. Rewire GT headlights, and consider upgrades like modern-type starter, voltage regulator, electronic ignition, halogen headlights, and replacement of the GT ignition switch.
Parts: 5019, 5025, 5026, 5078, 5050, 5027PM, 5016, 5060N, 6165.
Engine
Verify valves are adjusted, and test for compression. Inspect for leaks, and regasket if needed. Verify oil pressure measures "2" or higher on gauge at warm idle. Replace oil filter and use conventional 20/50W oil, plus ZDDP additive and camshaft oil dam to help protect camshaft and lifters.
Drivetrain
Inspect torque tube bushings for wear. Inspect rear axle gaskets and seals for leaks, including pinion seal. Inspect transmission case and lower pan for leaks, and inspect transmission mounts for wear. Check clutch and clutch cable for wear, and inspect rubber boots on bellhousing and cable for cracking. If equipped, check automatic transmission for leaks.
Parts: 7006, 7010, 7009 or 7019, 7016, 7018, 8011, 8012, 7002, 8001, 8021, 8022, 7003, 8052, 8045.
Suspension
Inspect bushings and hardware for wear, including ball joints, tie rods and steering rack boots. Bounce-test shock absorbers. Consider handling upgrades including polyurethane bushings, springs and sway bar kits.
Parts: 3013, 3014, 3015 3017, 3012, 3054, 3055, 3104, 3026, 3027, 3025, 3041, 3043, 3044, 3002, 3003.
Brakes
Replace rubber hoses. Inspect and consider replacing front calipers, rotors, and pads, and rear brake shoes and drums with new hardware if worn or sticking. Consider our "combo" upgraded master cylinder and booster, for optimal braking required for modern driving.
Parts: 4021, 4005N, 4001, 4009, 4013-22, 4037-9.
Body
Replace all old or cracked rubber to prevent leaks, both on the upper body and the underbody. If considering a repaint job, plan ahead and acquire all needed parts in advance of starting work.
Parts: 2001, 2002, 2003 or 2004, 2005, 2014, 2222, 2018, 2030, 2031, 6038, 3057, 4064, 9007, 9014, 12010.
