Rear wing weld points
The dots indicate contact welding seams.
The arrows indicate the gas welding points.
The rules for repairing the rear wing are the same as for the front wing.
1. When replacing the wing, remove the rear bumper, taillight, and reflector.
2. Empty the trunk. Remove the rubber seal, trunk floor trim, fuel tank (if the right wing changes) and disconnect the electrical wiring.
3. Cut with a thin, sharp chisel or cut with a grinder along the wing of the joint:
- with the rear wheel arch along the bend, retreating from the edge of the wing by 20 mm;
- with spare wheel floor (or fuel tank) along the bend, stepping back from the edge of the wing by 12–15 mm;
- with the rear panel of the body, stepping back from the connection line by 2 mm;
- with the rear window crossbar panel, 2 mm from the edge of the wing bend;
- with the rear part of the sidewall along the bend, stepping back from the edge of the wing by 15–20 mm.
4. Cut off the corner of the wing connection with the rear panel of the upper part along a horizontal line, stepping back 15 mm from the edge of the corner.
5. Drill out the spot welds where the fender meets the rear side roof panel and remove the fender.

6. Remove the remaining strips of the wing at the joints with the body and clean the seating areas of the body elements and the new wing with a grinder.
7. Adjust the new wing to the landing site and secure it with quick-release clamps.
8. Weld the wing with gas welding to the lower and rear part of the side panel, to the rear window cross member panel, to the side roof panel, to the rear body panel joint angle, to the spare wheel floor (or fuel tank). In the figure, the gas welding locations are indicated by arrows.
9. Check the fit of the wing relative to the mating surfaces and weld it using contact welding with a pitch of 40–50 mm.
10. Install and weld the wing reinforcements, using a gasket underneath.
