Spring chrome 110lbs. Girling 64543708
Chrome 110 lb rear shock spring, Girling 64543708, for Girling rear suspension units.
This is a chrome rear shock spring, rated at 110 lbs, cross-referenced to Girling number 64543708. It's one of the pair that sits over the rear suspension units shown in the swinging arm and suspension figures in the parts books, doing the job of soaking up bumps and holding the back of the bike up under load.

The catalog carries this under PN 99-1048 across a run of appearances from 1969 through 1980, which tells you it saw service across more than one model year without a change in part number, though the books don't spell out which specific machines it was fitted to beyond the swinging arm and suspension figures it shows up in.
If you're replacing shocks or just refreshing tired springs, check the weight rating and shock body length against what's currently on the bike before ordering, since Girling suspension units came in a few spring rates over the years.
