Wish to identify the year and model of these hubcaps

[lobster]

Hello all, I am trying to figure out what year and model Cadillac these hubcaps go to. I was wondering if anyone reading this could let me know? I am trying to help my grandmother remember which Cadillac that our grandfather owned and was part of that car. Thanks in advance!

The one on the far left looks like a '67

The second and 4th are 1970 caps. The 1st and 3rd look like 1966 or 67 caps. Fairly certain 66 cause I think the 67 caps were a similar to 66 but has small slits or vents. Others here may clarify.

This is also my understanding. 66 and 67 were the same style but one had the slits in the deepest part of the dished section.

#1 & #3 is 66/67.   I recently learned that the slotted version was a replacement to cure a harmonic vibration (whine) that occurred with the unslotted type, most pronounced on sedans acc to factory printed materials.  Why sedans I have no idea.

#2 & #4 1970.

1969 used the same wheel covers as 1968. That 1970 is a one year only cover.

I stand corrected. Earlier post edited.

I always liked the 1966-67 wheel covers but I don't know if they will fit over a 1968 or later with disc brakes. That's a pretty deep dish there.
