Drill out the rivets holding the regulator in place and then slide the regulator off of the window runners.
Installation is reverse basically but is easier with 2 people.
Holden sells the replacement rivets or you can use the replacement nuts and bolts.
this sounds really easy. i might have a crack this weekend. im wondering how much of a hassle it will be to fit though. im guessing lining up the runners with the regulator arm clips will be the hardest bit. i think a second person to help holding the window will help a bunch.
didnt turn out to be too hard. some tips i can think of are use 5mm bolts and nuts is ok instead of rivets. its just a little tricky to get some of the nuts on. do them up tight. u need a 10mm socket for the guide rail. bolt this on second i think.remove the regulator arms and also put them back in with the window about 3/4 of the way up, and have the winder handle close to get the regulater back down to the right place. you can also move it around a bit with the window to line up the bolt holes. bolt the 4 bolts to the regulator last. its easy enough to do with one person.
sorry its a bit out of order, but its just a few tips, not the whole exact process.
Definatley easier with two people. I did my front ones yesterday. I had to cut my dynomat off the access holes haha. Any way drill off the top off the 4 rivets holding the bracket to to the door. I used 4.5 mm bolts to hold the new ones back on. The regs I bought off eBay came with the runners. Undo the the other two bolts holding the other runner off. Make sure the window is near the bottom. Push the window winder bit through the hole and then slide the runners off the bottom window. Putting the new mech is an exact reversal. Having two people will make things easier. Make sure to put plenty of grease on the runner section!!! Can never have to much
its a lot easier to get a manual regulator out with the window 1/4 down. stops any chance of scratching the window etc.
only because of the winder knob.
short m5 (5mm) bolts are probly just easier to get (every bunnings, even big w).
dont hesitate to do it on your own. its only for window holding purposes u can use a second person. then u have to deal with stuff like talking to the helper and all that rubbish. easier on your own imo
