power steering pump loose 240D

1976 W115 240D, with a 1975 615 (220D?)

Hey everyone, I started having some serious belt squeal last week and finally came to the conclusion it was the power steering pump. I looked and found that I can literally move it by hand and the belt is obviously very loose.

I have tried and tried to figure out where the tension bolts are (if there are any?) as well as where the mounting bolts are and I cant find anything accept one 13mm bolt head on the bottom left of the pump (facing rear)

Of course I cannot fit anything but a socket head alone up there.

So if any of these questions can be answered I would really appreciate it:

Where are the mounting bolts?

How can I re-tighten the belt?

Do I need a pry bar, special tools etc..?

Should I try to secure the pump back to the frame first?

Can I realistically do this solo?

Thanks again for any info or direction

UPDATE: Ok I found a couple 13mm on the front and tightened them so now I cant move the pump by hand, so thats good, however I could not find a way to tighten the belt still.
