the very last paragraph is whats confusing me the most.....plus im not sure if im mechanically minded to be taking out parts from my engine :-(
i know that probably sounds stupid or something, but i actually dont have that much knowledge (which is why im writting this
) so i can understand hopefull more.
im not sure which company i would go to and not sure what measurement would need to be cut off......again probably somepeople are saying "just measure it" or something but just "measuring it" could be very hard???
i wish "eds" company, was just up the road 
sorry
