MikeM,

I just ordered one myself. I ordered it through Lowes, the manufact. is really "daws better built" If you go to their web page you can get the application guide and pick the one that fits. For me with the liner I have I picked a different one than the one you describe but it's close.

Mine has a 46+ inch bottom and a 56" top section. I'll post a few pictures when it gets here.
