Sidecar strut eyebolt, upper rear

This is the eyebolt to which your rear sidecar mounting prop/strut's fork is attached. Ural's catalog calls it a bracket.

If you need this eyebolt, most likely you didn't notice the nut loosening over time because it's under the seat and easy to forget about. So be sure to tighten that nut every 3,000 miles, if not sooner.

The threads are M12x1.75.

Note that this is longer than the eyebolt for the front sidecar prop attaches to the frame near the front wheel.
