If you use the flat washer and the lock washer, there might not be enough thread for the lock nut to do it's job. 2) The oil cooler lines are supposed to go on top of the bracket, not on the bottom. It appears that they are bent downward. If you are ok with them like that, then no harm done. 3) The rear compressor bolt needs to be put in the hole in the tab before installing the plate on the engine. I am sure you found out that you needed to remove the lower left plate mounting bolt in order to get the comp bolt in. It also may be easier to mount the comp on the plate, and install the compressor and plate as a unit. I have done it both ways, and it seems to be easier with the comp and plate together. 4) The third hole (closest to the crank) in the brace is there for the end of the factory screw to go into. It appears that your brace is sticking up a bit right above the pan. It is best to line all three screws in their holes before tightening any of the nuts. Also, leave the larger bolt loose in the plate, and tighten it last. There is no nut or new screw for the third hole, as it will hit and bend or break the tach pin....Rich

I have a definite answer for you on the lock nut. last week, I noticed that the belt for the compressor was squealing more than I have ever heard before. I had to shut off the A/C and pull over to inspect it. I noticed the nut was missing and the bolt had backed out. Upon further inspection, I noticed the last inch of the bolt was missing as well. I'm going to say that I bet it is still in the nut...

I went to the local depot and picked up a 1/2" x 8" #8 bolt and two nuts. I got home, chopped off 1" of the bolt, beveled the end at 45 degrees and hammered it through the bracket's bolt holes. I had to loosen the bracket a little to drive the new bolt through. I applied plenty of locktite and double nutted the bolt. I need to check if the nuts are still on the bolt, though - I have not popped the hood in a week.

Maybe a cause of the broken bolt but the supplemental mounting bracket on the upper oil pan is cracked at the 90 bend. It's not doing anything right now.
