Question, does anyone have a picture of how this bracket for the alt,mounts.
I know this is not right, but I'm trying to figure out the correct way of setting it up. It's on my 70 cst 10. I have cut a extension to bring it out away from the block. I have evan noticed that the fan on the alternator was dragging the bracket somewhat, I actually ground the bracket, so it would clear the fan.

on my 1970 c10, sbc350, I have the upper arm connected to the REAR of the alternator's top ear with the bolt going in from the firewall side. Also the engine end of the upper arm is connected to the head with the same bolt as the base, no spacer forward.

I've to attach on the back side, but the width of the bracket would not allow the bolt hole to line up with the bracket, i guess I could modify the bracket

You have the wrong adjustment arm. If you notice the one on zosoppp's engine has a lot more curve to it. That is the one you need so it can be mounted on the back of the boss that the bolt goes into.... I think it also has an offset where it bolts to the lower bracket.

Here is the lower end of the upper bracket.

Actually I was thinking that there might be a little bend in it from that photo, hard to tell, though.

Could be. A picture of the whole arm from more straight on would be the only way to tell for sure.
