thanks phil, lot of info there and i must admit if i had the chev and not the ford linkage then i would go ahead and fit the booster but unfortunately i don't so i will leave it off and put it back to original spec but thanks for taking the time to enlighten me.
i plan on getting the truck ready in time for summer. it will be the first green vehicle i can take out on the road and just enjoy driving it
cheers
