6' metal doors need replacement parts

Thank you for reaching out to us. You can use the 21-403 for the top and bottom tracks. For the bottom corner pivot pin, see the 21-002. You will need the 21-150 and 21-151 nylinders for the cutout holes so the pin can slide. For the top pivot and the two guide pins, you can use the 21-007, and again, you might need the 21-151 nylinder. You will also need two 21-277 track bumpers between the two doors where they meet. 

For each panel, you will need one 21-002 bottom adjusting pin and three 21-007 guide pins.
