Hope y'all don't mind me butting in with a related question. I need to replace the "rolling stock" on my (damn heavy) sliding glass door which is no problem. But shifting with the clay in this area the frame is out of square. Is this something a reasonably thoughtful guy can do himself or would I be making more trouble for myself?

Haven't looked into it at all yet, won't be warm enough to do for many months. The guys on TV make installing and squaring door frames look easy - but I've been mislead before.
