I had the same challenge as the OP and was using a professional windshield company to install it.
After 3 hours on the first attempt, they gave up and ordered another windshield thinking that was the issue.
Another 2 hours with the new glass and they still couldn't get it in. They gave up and told me I was on my own.
All of this was with one of the cheaper gaskets.

I ordered the Steele gasket and my wife and I put it in ourselves in about a half hour.
