You might be able to make them work, but that's not the mount that's used from the factory. You'll probably have to fab up some sort of mounting point to use those.
And for the record, I purchase that set from Amazon, and they are not OEM lights. The fit like OEM and look good, but one of mine fogs up all the time. I don't suspect they'll last too long, but I hear the same thing about the Hella lights too.
Edit: Those lights fit the trucks with round factory locations in the bumper. I'm not sure what year those started, but the older vehicles used different fogs.
I agree. Hella's been riding on their name recognition for a long time. Their products are made in china and not to the standard Hella once was known for worldwide.
Better performance from Cibie although it's tough to find their lights to fit a specific cutout or mounting.
