I spent half the day doing the same thing. Except our door is single swing door hinged from the center. As like Dirk, we also took out a sliding door (Pella) after the bottom of the door around the track wheels rotted away.
I still have to caulk, install some more window/door foam in the gaps and trim out the inside..
Neighbor hear the saw running and stopped in to see what was up. Said he was dodging his own Honey-do's.
So I put him to work helping carry it from the garage and fitting it in place.
