Hi Fritz,
I believe they are …. i have a spare one if you want it …. Vini if you get a chance to look at the blue one i would be very interested in the engine size…. looking at the doors it looks like a Cournil… One of the really old ones from the 70’s pre transcat…. you will know if its one of them if you look at the leaf springs on it ….. if they are very hgeavy duty (and the engine is 3.4L0 then it would be a cournil and i need one as spares ….. will ring the guy up and get back to you.
