This Porsche 911 Coupe SWB built in 1967 is a completely hard and damage-free car. It has been restored and made suitable for driving rallies and track days. The bodywork and engine of the car are matching numbers, and the original color of the car is Hellelfenbein. The engine was built by Duel in the Netherlands as a 906 Race/Rally engine and equipped with double ignition. The gearbox is designed as a close ratio box with a limited slip differential. Both the engine and the gearbox have been overhauled by Duel in the Netherlands. The chassis of the car has also been overhauled and made suitable for sporty driving. Furthermore, the 911 is equipped with a 100-liter tank.
As a starting point, we took a 911 from 67, with a 4-speed gearbox and matching numbers. The body was in exceptionally good condition, but the paintwork was a bit poor and was repainted. The car was very original and damage-free.

Box number used: 7190129 type 901/07 5-speed box overhauled by Duel in Heerhugowaard and built up as a close ratio rally box with a 904 main axle and ZF limited slip differential. The car was delivered on April 7, 1967, at VW Pacific in Culver City CA to a certain Michael Niellbert from San Diego. The kardex is present with the car.
