Default need a little help identifying some front accessory bolts

When I got my LS1 it came with a box that had some front accessory bolts in there. They weren't labeled except for "front accessory bolts," so I'm trying to figure out where these miscellaneous front access. bolts go. Thought I'd post here to ask since people are always building these engines. Hope someone doesn't mind checking these out...

I believe these two go to the alternator (top two on the alt. bracket):


And I think this one is also an alternator bolt (bottom one on the alt. bracket):


These two I have no idea; do they go on the small rear alternator bracket?:


No idea on these two:


Here's a shot of them in relation to each other:


And here are the diagrams and sizes I found for the LS1 front accessories:







Thanks again guys

I'm at work and have to get home to look at my car for sure.............. I just swapped a motor in a 98 and had my hands all over this. I can guarantee you that these are for the alternator or the compressor without a doubt. None of the other accessories have that size of bolt on them or in them.

The 2 longest ones could also be potentially for the motor mounts

THANKS MAN. Ok cool, I think I got it on the alternator bolts except for these two:



So those ones^^ are the ones that go on the rear bracket of the alternator (#2 and #3 in the first diagram I posted)? In the diagram it says that the smaller bolt is 35mm in length, but those two in the above pic are about 55mm and 50mm in length.

I completely forgot about the compressor; I'll search for that in the parts diagrams I have, see if the other two bolts match up to that. My LS1 is a 98 also.
