Ami I missing an engine mount bracket bolt?

I didnt watch any youtube vids b4 I replaced the tension pulley and I removed the engine mount and the bracket it bolts to. No I am having trouble either I lost one of the bolts or I got a bolt that goes to somthing I dont think I took off. I removed all but one from the bracket (looking from passeneger side- top bolt on the right) I I just pried the bracket over to get access. I took out 5 bolts and I have 5 bolts in my box but one of them is different. I noticed 4 of the bolts(10mm) have an 86 on the head and the mystery bolt says 1/2 and it is a little bit short and has a point on the end like a wood screw. Ive tried putting it in a couple of the bracket holes but it just pushes straight trough. Do I have an 86 bolt in the wrong pace or am I missing a bolt? And is that something I can get at the hardware store?

Thanks

1)You should have 2 nuts- these hold the bracket to the frame of the car. These are identical. And they will not fit the bolts talked about below. If somehow you took the bolts out also (not sure how you would do that bc i think they are welded to the frame) then these also are the same.

2)Then you should have three bolts or 3 nuts or any combination that leads to three (such as 1 bolt 2 nuts, 2 bolts 1 nut, etc) that hold the mount to the engine itself. These are all the same.

So assuming you removed the two bolts from 1, and 2 of the 3 bolts from 3; then you should only have 4 bolts.

That extra bolt you have doesnt match any others and doesnt fit the description of any bolt on the s-series other then the bolt that holds the battery tray from inside the wheel well.
