Do you know a cross reference for it? The left is Fiat 126, the rigth is Mondial Image Unavailable, Please Login
I recall a thread that the dipstick parts may cross to a Fiat Uno. May be the one you have identified already that is smaller though. Might check different Uno model years. https://m.buycarparts.co.uk/original-imperium/9406754 Here is the whole new unit... https://www.partscollector.com/en/mostraArticolo.php?IDArticolo=6475
yes, that one is the rigth one, its smaller than the left one (the mondial one)... Fiat Uno of all years use the same.
