Well i have just started to attempt the swirl flap mod and there are 2 nuts missing from the inlet manifold, no idea why? Been trying to get some replacement nuts has proved to be a nightmare, as they are 7mm flange nuts, everywhere ive been has got 5,6 or 8 mm nuts in stock but not 7mm. So has anyone local got some spare or know where i can get some? Cheers Phil
