HELP!!! I need to know how = to install a sliding side window and the big hatch window. I have new glass, = the old ones are out, the rubber is pristine and now ready to put them back = in. Do I need two people and use that old string-in-the-groove trick? = Need to lubicate anything? The vanagon doesn't run so I can't take it to = the glass shop and they want $100 to make house calls. I know many of you = have done this before and I've done it on many a beetle but these windows are BIG!!
