Help finding my closet door hardware

I checked a previous post by some one else that fortunately for them, they had the square hold to work in the mechanisms into the doors to connect to the track. Unfortunately, my doors do not have the square hole, just two round holes of the same size as two alternatives to insert the pins. I need 3 upper guide pins "BM-1R-9",and 3 Slide Bushing "BM-1R-10" slide bushings with 3 "BR-1R-5"springs and 3 "BM-1R-17" Grommets. The serial number for this old gem is 101356. Can you offer any assistance in getting me these parts? I have attached a schematic of the doors as well as a photo of the location of the holes. Suggestions? Thank you in advance.

Attached is the requested photo showing the assembly of the guide pin, spring, slide bushing and rubber grommet The rubber grommet pictured below the pin only functions as a means to keep the pin from sliding out once in place. (not really necessary) The only item I found on your site was a pin with the spring encapsulated in a plastic assembly that would not work with my door not having a square hole to work it in. Suggestions? Thanks Again.
