Your pulley setup was probably originally LA LD ZP with a 6.1" pump if the car it came from had AC.
Since you have a 5.6" pump on there KF water KC crank & KH powersteering would work for you.

 

Excellent! Nice to have something to search for. I have just taken the PS-pump out of the car, but lack the tool to remove the pulley. Will try to pop by a shop that can do it for me.

Will my double grooved AC PS-pulley work with the non AC stuff? In my head I imagine that the inner groove would do the same job as a one grooved pulley - but I guess I'm not so lucky?

 

You, sir, are a disturbed individual, and we should all be proud to have you in this group .

Yes indeed. Thank you very much! As soon as I get confirmation/disconfirmation about the PS-pulley, I'll post a "wanted" post for the correct pulleys.

Looking SO forward to getting this problem fixed.
