Timing cover bolts on L67
Hey guys, I dropped my motor off to the machine shop to have them bore the cylinders and mill the head surface. However I didn't know that they would not reassemble the engine afterwards, and now I have an assortment of bolts unorganized. I went to the dealership and checked out their catalog of what is supposed to go where and so now I am at the timing cover. I've determined that 5/16'' bolts go on the front of the engine and 8mm go on the rear main seal housing. Here is the information the dealership gave me:

So I am having trouble deciphering the stuff in between the lengths such as why call# 332 has a 2.75 and a 3.07 length. Also not sure what 2AX1.50 means for #334 and what full 1.0 THD 300M PO means. Nonetheless it'* not terribly important to me. Here are all the 5/16 LONGER bolts I could find (tested with a 5/16 nut) and I am assuming these all go to the timing cover.

I also found these smaller black 5/16 but I'm not sure if any of these go to the timing cover as well, or where they go for that matter.

In any case I really appreciate anyone'* help. This is a project thats been going on for almost a year and a half and I just want to finish it!

What about the long one with the funny head? I'm guessing that is 332?
And the remaining long ones (top row) are 334,335?
Also, if you notice, there are two short, big head bolts with washers at the end. These ones are slightly longer. Are they for the balancer shaft retainer?

So I noticed that the snaps on the bottom front cover bolts are meant to hold a plastic retainer for the harmonic balancer. How important is this retainer? Some of the portions where it connects to the snap seemed to have broken off when the engine was first disassembled, so I am trying to get a sense whether it'* worth installing or even getting a new one and what harm could arise by not using it.

Helps keep the dirt away from the sensor. And also holds the cam sensor wire away from the harmonic balancer. See if you can stick it in place with some RTV on the clips.
I just noticed that my timing cover gasket kit came with 4 o-ring seals. I have looked at the diagrams in the FSM some 10 times but I don't see them anywhere. What are these for?
Here is an image of the felpro kit on amazon, the bottom 4 seals are the ones I am looking at:
