Timing idler bolt size

[Rob0985]

I have torn down to replace oil pump and timing chains in my 03 ram 4.7 and well the timing idler pulley (the center one with the 3 sprockets for the chains), is missing. Anyone have any idea how I can find out the thread size/type bolt needed without a bunch of back and forth guessing?

Take vin to dealer, order bolt and the pulley.
