Critical Body

Rear Quarter Rust

Symptoms

Rust in the rear quarter panels, behind and below the rear wheels. Bubbling paint, perforation, structural deterioration.

Cause

The rear quarters on the Torana trap road spray between the inner and outer skins. The complex shapes create pockets where water sits. The dog-leg area where the rear quarter meets the sill is particularly vulnerable.

Fix

Cut out rusted metal and weld in new sections.

Reproduction outer quarter panels are available from specialists.

The inner structure may also need fabrication.

Budget $1,500-3,000 per side for a comprehensive repair by a skilled panel beater.
