An update:
Fitted the rear electric windows kit from goldie today - all working as it should and looking smart.
It appears that some ham fisted work has been done to the n/s/r door before as the interior handle was glued to the door card, apparently because the three clips that hold it to the door had been snapped off! Anyway had the replacement handle from goldie so after carefully freeing the old interior handle from the fabric with a stanley knife was all ok.
There was also some similar sledgehammer work done to the centre console with a few clips snapped off but I've still got the console from my mk1 so in that went with the switches.
As usual nothing is quite as simple as it should be with the zed but it's all part of being an MG owner and I love it
