I was driving down a Sask. gravel roads, pulling a dog trailer, when a rock bounced off the trailer and blasted my passenger side rear window (the one in the little rear door). Where is the best place to find a replacement? I don't need the defrost, so I thought I would just replace with a custom cut piece of safety glass. When I went to Speedy Glass in Swift Current, the guy there said that there was enough of a curve to the glass that a piece of safety glass would break on the first real bump. In, Calgary, a replacement Toyota piece of glass is upward of $400.00 dollars. Is this my only option? Any help would be appreciated. Thanks in advance for your time.
