There are 3 bolts for each hinge (which mounts the hinge to the bay). One of the bolts has a bigger washer, the other two have smaller size washers. I am assuming that the bolt with the bigger washer bolts into the forward hole. Correct?

I dont have a picture handy but I'll see if I can find one. The one with the large washer goes in the upper rear if I,m not mistaken.

I agree with upper rear, definately not in the front.

Upper rear is correct. John.
