Original floor mat carpets in 1974 and 1976/1977?

[rsnodgrass]

Does anyone have photos of a set of original floor mats for a 1974 model? What about original floor mats used in 1976 or 1977? I've had a heck of time searching trying to find any truly original example. I think the 1974 version had rubber on the front half with ribs on the rubber section. I have no idea what was used in 1976 and 1977.

Thanks.
