Acme 17-4405

A contractor from Naples Fl says:
I understand that acme 17 -4405 has been discontinued. Here are photos of a 48" and 30" inch set of mirrored bifold doors to repair. I believe I could use
3 screw driver bottom 21-092
6 pivot blocks 23-181
3 bottom drivers with rollers

Am I missing any hardware that you might see from the pictures? The top track and rollers are all fine not sure if I need new corner blocks as well if this hardware adapts to it I should be just fine. Thank you for your time.

To use the bottom the 21-092 adjusting pin, you will need the 23-407 bottom corner block. If you want to reuse your Acme corner block, then go with the 23-113 adjusting pin. The roller guide would be the 21-174 and the spring loaded pin that goes with that is the 23-115.
