Folks, Here's picture of the rear mount track support that I need. The track is 1 1/8" at the bump close to the end of the track. It is barely inside the holder. I've looked at 32-028, 32-003, and others but don't know which would work. The track was installed about 40 years ago. Your help will be appreciated.

I believe part 32-003 may be the closest replacement match.
Carefully review and compare the measurements to determine if it might be a fit.
