1974 Triumph GT6 Mk 3.
The rear panel and valance was rusty and much repaired necessitating its renewal.

The only panels unique to the GT6 when compared to the equivalent Spitfire are the bonnet centre and the roof and rear quarter panels. The rear wings are nearly the same - the GT6 has a fuel filler recess in the near side one. You can only get Spitfire wings so the fuel filler assembly has to be transferred from the old wing.
