I'm not sure exactly, I've heard stories of sliding a piece of cloth underneath and pulling it sharply, however for a vx you'd wanna be more gentle I guess.
You can by the winder winder removal tools, probably from supercheap
Yep go for the bike tyre lever or get an old flat head screw driver n bend the end to like a 45degree angle this makes it so u can get round the bak of the winder....heaps easier than trying to do it with a butter knife as it wont be pressing against the door.....
ohhh i dont envy you having to find it. ive had them fling so far accross the shed its not funny. and if anyone knows my shed the chances of finding it between wood shavings and car parts is slim.
