i purchased a window regulator on
. the mark 1 as with other models have the same inherant probs regarding regulators. the mark 2 has a much more reliable mechanism doing away with those silly white clips. which will fit the mark 1 model. when our replacement arrived we found that we had to take the mounting bracket of the motor and place it on the reverse side useing cut down rawlplugs as spacers. saves haveing to cross over the cables so the runner and the motor are faceing the same way. what a farce but it worked a treat.seems no matter which side you order os or ns unless you do as i did the only joice is to cross the cables. fixed the drivers side now the bloody passenger sides stopped working. here we go again.
