Stanley bifold door parts

I need to find an additional top swivel bracket for a ~ 1980 vintage Stanley bifold door kit. Looks like the pictures. Bracket is 1.125" wide, about 2.25" long and inserts into the track shown in pic 6539 that has a profile 1-3/16" wide and ½" tall. I also need a lower pivot bracket but haven't taken pics yet. The top one seems to be the hardest to find.

For some reason I was unable to post on your website because it did not recognize my email as a valid address. Incidentally I just ordered a couple roller pins for the doors that fit perfectly into the channel SWISCO's 23-172.

Thanks Paul. I've decided the 23-302 bracket is too narrow to work on my 1980 vintage Stanley track so I've ordered a 23-509 track and associated top and bottom pivots, bottom bracket and top guide to replace all the hardware on my 3 foot wide bifold doors.
