Gas support struts (one pair, left & right strut) to hold the bonnet open.

These support struts are specifically designed to work with the EU mandated pedestrian safety systems fitted to all European Fiat & Abarth 124 Spiders.
Unlike most of the cheaper struts available on eBay & from china, these struts don't interfere with, or in any way damage those safety systems.

Fitting is incredibly easy and only takes about 20 minutes. You only need one socket / spanner (M12) to fit the struts.
