All
Porsche® 914/4 and all 914/6 tool kits came with a tow eye-hook. This item, unique to the Porsche 914 models, screws into the rear bumper to enable track towing and roll-back truck loading without damage to the valence or suspension components.
The Porsche 914 tow hooks are cadmium-plated in either a silver or a gold
color, with the gold being much more common.
The color included does not appear to coincide with any specific year or
model; it may have been indiscriminate.
