Hi Susan,

I know nothing about AGP installation, but I do know that a difference of 4.5 inches side to side is NOT a good thing. I'm bumping this post up so that some of the installation guys on the forum can get a look at it and hopefully answer your questions. Please try to be patient with us, though--we are being swamped daily with new posts, partly because it's just that time of year, and partly because more and more folks are having problems due to the warmer winter a lot of us had. Hopefully somebody will be along soon that can be of help....
