I haven't looked into it yet. I want an idea of these alternatives
first as I was told it would be a few hundred dollars more to get the
custom size. If for those same few hundred dollars I can get a six
foot door and not have to worry about the size next time it needs
changing (by myself or future owners), then I would prefer to go that
way.

Thanks for the suggestion, I may have to look into it..

Have you tried to special order a new door the right size?
I've done it many times (not that type of door), but it doesn't hurt to
ask several places.
