my friend is putting a new water pump on his 94 mustang 5.0 L and we ended up pulling the timing cover off as well.... needless to say it needs a timing chain and gears... it has a double roller on it now, would pefer a double roller but would take a stock set as well. if you have a set please pm with your number and ill call you asap. we would like to get this done tonight or sunday. thank you!!!
