Metal Bifold Door Hardware

Hi, sorry I don't have better pucs at the moment. I was hoping you might be able to ID the door from these lower guide pin pics and provide a parts list for all the hardware. Or maybe point me in the right direction for how to ID them, I couldn't find a brand or anything.

My parents and several of their friends (likely the whole subdivision) all have these metal bifold doors in various sizes with various missing or broken parts. At the moment I'm needing bottom guides and pins for the sliding part, but a full kit of all the parts would be handy, these houses are early to mid 70s, so there's a lot of them to be fixed.

Thanks,
Glen

I finally found a label on one of them, they are Leigh Full Vu. I found another post asking basically the same question and it was answered, so I think I'm all set. Thanks
