need a part number

[Beigg]

Doing the balance shaft chain assembly for a 1st gen 2.9L Colorado & am in search of a driver side balance shaft end with the center bolt. A part number for the end piece would be good, I do not need the entire balance shaft. I'm uncertain if the 3500s & 3700s are the same.

it goes to the item #1 in the attached.

For anyone randomly looking for the above, it is only available when ordering the Part Number of "12578390"
