I'm thinking of replacing my soggy 15-year old garage door (something
like particle board) with a plastic or steel one. I have myself
installed rebuilt torsion springs, lift cables, and a bearing, so I
know how to work on this aspect. What seems daunting is replacing the
track and all the brackets and supports. So is it possible to just
replace the panels and lift hardware, or are doors and tracks too
brand-specific to do that?
