Rust Prone Areas:

Wheel wells, rocker panels, floor pans, strut towers, rear valence, and around window seals are common areas for rust due to age and construction.

Carburetor Issues:

Wear in needle valves and seats, sticking throttle linkages, and vacuum leaks in the SU carburetors can affect performance and drivability.

Electrical Gremlins:

Aging wiring harnesses, corrosion in connectors, and failing relays are common on vehicles of this age, leading to intermittent electrical faults.

Suspension Wear:

Bushings in control arms, sway bars, and differential mounts can degrade over time, leading to poor handling and noise.
