trying to find a 30x80 mirror bifold door with standard 3/8" peg, top track only
 

I've been trying to find a replacement door for a closet:

- 30" x 80"
- mirror bifold
- top track only
- standard 3/8" pegs/rollers

I've turned up a lot of options (I'm in the Boston area), but they all use proprietary track/roller sizes and require installation of a bottom track/guide in addition to the top track. I'm really hoping to find another mirror bifold to replace my old one that will just pop-into my existing standard 3/8" top track. Any help would be very much appreciated, thanks!

You may have had a wood door that someone glued mirror to.
