Took out the stock location Precision Intercooler. The Precision water pump bolt that comes with the intercooler is longer because of the aluminum spacer. What size was the stock bolt?:biggrin: Measured the Precision bolt length and subtracted the length of the spacer. Gave the paper I wrote measurement on to my wife to put away. Well....she lost it!:biggrin: Accident? She thinks I spend alot of time in the shop.:biggrin:
