Right, I wish to de wiper my lupo at the rear. I pulled the black plastic cap off at the base and there was a wee nut. Is it just a case of un-doing this nut and the wiper assembley comes away, or is there more to it? Ofcourse I will be filling the hole with a nice grommet but what size grommet is required. I'm sure I read somewhere it was a inch or 25mm one. Also tonight I picked up a set of eibach springs to lower me loop. Realistically how hard are they to fit? I need my car everyday so it is not an option for me to have it off the road for a great deal of time. cheers, timbo
