Good: I have a new old dresser!
Bad: The drawers in it are old and the wood is splitting, the rail guide on one came off completely and took some of the plyboard with it
Good: I still have drawers and roller rails from a dresser I disassembled!
Bad: I'd have to do a lot of trimming and refitting to get them on the current dresser
Worse: I'm not a carpenter
Even Worse: despite that I still have a saw and sawhorse
This can only go well
The best thing to do would probably be to just take one of the loose boards and replace the damaged plyboard with it, not try to refit the whole thing, since I only have so many spoons to budget and I've still got a lot of apartment maintenance to do
