Is the cam on bottom of 1999 Kitchenaid side by side refridgerator door a 2 part cam?

I found a 1 part cam on website (part #AP3046922), know I need this part. However, I was expecting this to be a 2 part cam that would fit together. My cam is worn down near flat so I don't know what it looked like. But when i looked at the (reversed) cam on freezer side of this side by side unit, its appears that this cam should have 2 parts (top and bottom). I'm hoping I can figure this out before I pay for O/N shipping for the wrong or incomplete parts to finish the job.

Thanks!

Actually the picture of the kit Mr. Denman showed you is kit that has many cams in it. It is a kit. In fact, I just bought one yesterday for my customer tomorrow, and I bought the lower hinge, where the door sits on, and then the lower cam is on it, already installed, and then in that kit, there is the one that screws in on the bottom side of the door. So to do this job, no matter what kit you use, you have to take the door off. Once the door is off, flip it on it side, and then replace the one on the door. Then replace the one on the bottom hinge. So, yes there are two!! Tom ApplianceEducator.com
