50's wood closet sliding door

I have a 50's ranch house with wood sliding doors on the closets. Each closet has 3 doors so the middle door is passed on each side. They have a wood floor track and the doors have a plastic guide screwed to the end of each door with a small tang that extends into the wood floor track. This small tang has broken off and without the tang the doors can hit eachother and stratch them when sliding.

I have not been able to find a replacemant.

I will get pictures this weekend, and they should tell the story.
Thanks,

picture attached. As you can see from the picture there should be a tang extending from the bottom into the groove to keep the door rolling straight.
Thanks,
Jerry

I see picture of part 67-008 and it appears that it could be modified to work. Thanks, Jerry
