Indeed. Excellent looking build
I looked back at the box top and saw the markings. So, your kit is for the GT40 Mk.IIB chassis No. P/1031 as she appeared in 1966 - as race number 2, dark blue paint, single 4-bbl Holley carburettor, twin rear-deck scoops, and twin aluminum 'suitcases' (for Le Mans). BTW, this car won the 1966 Reims 12 Hours event.
After its 427 later seized, the car was 'hybridized' with parts from P/1047. That second car's chassis number was re-assigned to the former 'Blue 2' ... with chassis number plates being switched around for slightly shady racing reasons. This car re-appeared for the 1967 season and that's where is gets even weirder.
One GT40 Mk.IIB (chassis No. P/1047) appeared as 'Light Blue, race No.57) alongside a revitalized - or re-number plated
- chassis No. P/1031 (maroon, race No.5). [1] So
why am I telling you all this? Well, chassis No. P/1047 has been preserved (as 'Light Blue 1') at the Revs Institute Collection in Florida. The attach photo of the rear end clearly shows 1966 Chevrolet
Corsair taillights. So, taillight mystery solved
https://revsinstitute.org/the-collection/1966-1967-ford-gt40-mark-ii-b/[1] The Revs Institute says P/1031 No.5 was 'gold' in 1967, confusing it with 1966's race No.5. BTW, the distinguishing features for 1967 were twin 4-bbl carburettors and wider tires (necessitating 'flared' wheel arches to stay within 'covered wheels' rules).
