The compensators have been stretched on both of the ZTs I have had, they start like the one on the left and end up like the one on the right, which is why you often end up out of adjustment, plus they spring as well which is why it is often difficult to get the handbrake to hold.
I converted both of mine to stainless steel shackle which is easy enough to do as I had a spare one. The D link is only a few of quid on Ebay and you just knock the pin out and change the link over and peen the pin back over.
