Due to my terrible organization I have mixxed up some of the bolts, and I'm trying to figure out which ones go where. I mixxed up the ones from the alternator, a/c compressor, starter, and the rear accesory mount. Since I've replaced the starter a half dozen times I know which ones they are. I just need help figuring out the a/c compressor and the alternator. The new engine came with a rear accesory mount so those I'm not worried about.

The two types of bolts I have that could be for the a/c compressor are as follows. One is about 3 inches long it is a 15mm head and the marking is 98 M. The other one is slightly longer and the very top (near the head) has no tread and I belive it is a 13mm bolt (don't have that one in front of me). I tryed taking a picture, but my stupid expensive camera isn't working right (pics were very blurry). Hopefully someone can figure it out from this description.
