My question was just general, i'd love to buy the set but the additional cost of shipping to the Netherlands, import duty and taxes makes it too costly i'm afraid.
But it might be good to know for other potentional buyers.
I took some measurements tonight and there seems to plenty of room. It is well below the carburetors and below the top of the radiator neck. So, I would say it is good.
It is a good period correct "hot rod" modification.
