1970 Duster project in Sweden

I test-fitted the alternator to see if I had the right brackets. It seems I have, but that I might need to shim it forward a little to get the belt in the right place. That is good because it is very tight at the backside of the alternator and the front of the Edelbrock head. Some pictures before shims. This is the way it is supposed to sit on a 360 right?

Then I ran into problems. My Steering pump brackets are not right for the 360. This pump and bracket came of my old 273 engine. Can you help me identify which pump I have and what brackets I need? I can go with aftermarket stuff. Can I make this pump work for me or do I need to get a replacement?

This bracket on the right is the only thing that came with the engine when I bought it .
