Ok, finally got a fresh rebuild done on the 1.6 it's out of a 91, I'm used to mk1 drive belt set ups so I was a little surprised when I went to bolt up my old alt and belt.. It's got a weird set up and I don't know the drive belt diagram can anyone help me? Do I need to get a newer mark 2 alt, and if I do that, can I run a belt set up with the alt, water pump, and crank or does it need a ps pump? I don't really want to pull the whole bracket because I'll have to pull the ip again any help here guys?
IF it was an A/C set-up originally - that you're dealing with (new engine pieces) - you'll need to mount an a/c compressor.
If the engine is going into an Mk1 - you would have needed to swap the passenger engine mount / Inj Pump bracket from the Mk1, and probably would have been good to use all the other Mk1 parts/brackets.
Is the engine installed in the car ?
I may not be understanding everything clearly.
I'm not looking directly at an example, but have them in the driveway and in other places, Mk2 engines with and without a/c, Mk2 cars with a/c and pwr str. If any of that would help for needed info/pics from them.
I had a similar problem. I purchased the AAZ serpentine setup because I could not locate the correct veebelt alternator and pullies
I used my MK I gasser alt. I had to cut it and make a bracket out of a turnbuckle, but for a single V belt this is pretty good. I just cut the mount on top down and used washers to shim in each direction. I also had to drill the alt. for a 12mm bolt as the MKI gasser had an 11mm. Shown here:

You can get a new 1.9 aaz alt ( a/c ) type bracket with arm/roller for 185.00 from the parts place
different alternator is used also 90/120 amp
