You are welcome. The pivots for the vertical plane are made of rubber and replaceable. The original ones are nearly always perished.
Look behind the pivot assembly, on the plastic silver cap the wand sits in, there is a screw holding a half moon shaped washer. If you remove the screw you will be able to lift the cap off and see the vee blocks. Take care not to pull it too high, there is an earth wire which if disconnected is a pain to fix.
In the photo you will see the knife edges and the vee blocks they sit in. Please disregard the sweet wrapping looking stuff wrapped around the knife edges. I have no idea what it is.
What you can see in the photo are the white rubber bits, these are the bits needing replacing. You can buy replacement vee blocks on ebay.
As a footnote, I would not use the arm as it is. There is no way to stabilize azimuth, the spacers will not work for long.
