If you're ever in Adelaide and need a windscreen repaired or replaced I can highly recommend Windscreens O'Brien at Greenfields on the northern side of Adelaide.  I recently took my 1993 Winnebago Motorhome there for replacement of both front windscreens as the driver's side was almost falling out and the passenger side had stone chips. The first one went in quickly with no problems but when it came to the driver's side they found the windscreen wasn't fitting in properly which was probably why the existing one was almost falling out.  They worked on it for hours resorting to some body alterations, grinding around the edges to try to get it to fit but still weren't 100% happy with it so I left the vehicle with them and collected it 2 days later.  I was very happy with the original price they quoted me and amazed when they didn't charge any extra for the additional time it took. Also they were the only ones I found who could source the windscreens from o/seas and were interested in doing the job. I now have two lovely new windscreens expertly fitted with no leaking (have had heaps of rain since fitting) and a warranty if any problems arise.  A great job from the boys at Windscreens O'Brien Greenfields.
