Hey Leon,
Your fast glass motors look good, they just sit over the normal winder mechanism then?
have seen aftermarket kits with cable driven motors for about 350/pair, considerably more than your 12 bucks, but they come with slides and stuff too.. very trick. go to
http://www.airide.com.au (i think..)
I agree the jaycar units are crap, I tried to use them on my old bedford, but they're not strong enough to pull a skin off a custard.
Wiring is pretty easy when u get into it huh... it's just a huge PITA.
my $.02 on something I no naught about lol.
Cheers
Ed
