older bi-fold mirror door, metal

A quick learner from Phoenix says:
Not sure what I need. Some of the bottom pins and plastic guides that go in the floor track are missing, and one of the pins and guides for the top track is missing. 1974 vintage.

We'd like to recommend a few parts that may work as alternatives for what you currently are using. Please take a look at the following parts: the 21-108 pin cap, the 21-050 bifold door guide pin, and the 21-049 bifold door guide pin with out the spring. We recommend to look over each part to see if these are the best match for you. 

A quick learner from phoenix says:
Does the 21-050 contain all the little pieces shown, or is it only the pin?

Good Question! The 21-050 contains all the small pieces you will need. So, your order will include the pin, pin cap, nylinder, push nut, and spring.
