I have an old Fenestra bifold door. It looks like the 21-065 in the one I need only my pin is 4 inches. The plastic guide is .375, the pin with is .30 and the length is 4, and the spring is 2inches. I need the complete assembly.

Hello,
I think you're right on target with the 21-065. Don't be concerned with the pin length, that is not a critical component in the performance of the door. Thanks for posting!
