I used to be really into 60's VW's when I was younger. I could install both windshield and quarter windows in under 15 minutes.This thread is 20 years old but I can say I just replaced my fixed glass on my '99 escort SE. The quarter circle shaped window behind the rear window. It was a breeze. Side glass is usually fine, but my experience w/ windshields is it's worth the money to hire the pros. Windshields are a pain in the windshield. Never again.
