Funny ... I just ordered this Salamini sticker because I thought I remember seeing it on a similar S2, but now I can’t remember where it goes. Can’t seem to find any images on the internet showing the placement either. Hope someone chimes in.
IPRA was the supplier of radiators for 105/115 cars.
When ordering from most all of the Alfa Romeo parts suppliers you will need to do your homework. They offer a very limited selection of stickers that are only applicable to a few cars.
Early 105 cars had a sticker placed on the radiator with a warning. Starting in 1967, the 1750 got a radiator cap sticker. The 2l cars also got a radiator cap sticker. The Juniors all got a yellow/black sticker on the radiator but it was slightly different from the early 105.
