OK, I didn't mean for my post to sound like I was making fun of anybody, i'm sorry if it came across like that.
Years ago when I was working on my build, I went through exactly what I see many people going through now, -trying to find glass to fit my G28 build. After months of searching for donor glass, I came to the realization that their is not going to be a donor glass that will fit the opening exactly like it needed to be.
Autotemp offered to make the glass for me, all I had to do was send them an exact template of the shape, and what radius curvature I needed. I had to pay a $1K set-up/tooling fee ($500 each side), and then $160 for each set of glass, with no minimum order. I ordered 5 sets (10 pieces), and they arrived about 8 weeks later.
So now, Autotemp has my jigs to make my glass anytime I need it. They still charge $160/set which I think is a great price, but they also charge $300 for crating and shipping, no matter how many pieces you order.
If 5 people here wanted a set of glass, it would cost 5 X $160 = $800, plus $300 shipping for a total of $1100. Divide that number between the 5 sets, and each set would cost $220. Shipping from me to anywhere in continental U.S. is an additional $43, bringing the total cost to $263/set.
