Fiat Dino Forum (FDF)

if you look at the picture,the top left is a complete unit,bottom left is the whole rotating top half (made of two parts) as viewed upside down,top right is what you have,bottom right is the same as bottom left except its the top view and without the central spindle which can be seen in top left picture.hope this helps. You should be able to buy them used but beware some unrealistic asking prices.
