Tyre security bolt WM3
A WM3-size tyre security bolt (rim lock) for the rear wheel, keeps the tyre bead seated on the rim.
This is a tyre security bolt for WM3 rim sizes, listed in the parts books under the rear wheel section. Also called a rim lock, it clamps the tyre bead down against the rim so the tyre can't spin on the rim under hard acceleration or braking, which would otherwise shear the valve stem off and cause a flat.

Appearances in the catalog run from 1970 to 1972 tied to WM3 rim fitments. If you're not sure your rim is a WM3, check before ordering since rim locks are sized to the rim width.
