parts needed!

Hello,

We suggest converting your door to use Slimfold door pins. To do this, you will need to replace the tracks as well.  We suggest doing one set of doors with a pair of tracks, one 21-001 bottom adjusting pin, and three 21-007 spring-loaded pins per panel. You will also need two 21-277 bumpers and if the old bushing is worn, see the 21-149 grommet and 21-153 bushing. For tracks, we offer the 21-404 (48"), 21-401 (36"), and 21-402 (60"). Thanks for posting. 

Yes, you would need two tracks for each door, one for the top and one for the bottom. The 21-001 bottom pivot would engage with the 21-200 bracket that comes with our replacement tracks. 

I see what mean. The frame being damaged also doesn't help. I'd suggest going with a 21-002 bi-fold adjusting pin. You would remove the nut and washer, then slip the pin in place from the bottom of the door. Once it is through the door, install the washer and nut. Then you should able to adjust the bottom pin.
