BB AC bracket help

[1-PU70]

I just replaced the compressor on my 70 BB and it turned into a pain. When I had the motor rebuilt the same shop pulled it, rebuilt it and replaced it. Man it killed me to let someone do it but when your working 1500 miles from home I had no choice. Well when I took the old one off half the bolts were missing and I think there is a stud for the exhaust manifold for the lower bracket and maybe a spacer behind the rear mounting plate I cant remember. The problem is the rear brace. I cant figure how to get it on. It doesn't line up with any holes. I know it did it was on there before the rebuild. I think it goes from the rear adjuster bolt to the rear lower pivot bolt. So can someone take a bic of the rear of the compressor on a BB maybe I can get it back together. Thanks Gary
