Don't know where you're located 75 (don't see it in your signature), but take that first Special Note to heart. I know it's summer, but if you're anywhere that gets cool, don't try to fit the top unless it's nice and warm.
Really warm. The warmer the better.
They're understating it a bit by saying "might shrink an inch or more. Making it hard to install." If it's cold, it's likely to shrink 3 or 4 inches and it's pretty much impossible to install under those conditions!
So if your weather is warm, now's the time. It's been getting really cool in the evenings and mornings around here, so I thought I'd mention that aspect specifically.
Have fun. Measure twice, drill once. ;D
