First photo shows '71 offerings, other 2 photos show '72 offerings. There was a realignment from 3 trim levels from 67 thru 71 to 4 trim levels in '72.Deluxe went to Custom. Custom went to Super Custom. Super Custom went to Sierra. Sierra Grande was now a new trim level for '72. During '69 thru '71 Sierra and Seirra Grandes models did exist, but they were considered additional option packages not trim levels. In '72, they were no longer options packages, the Sierra and Seirra Grandes were trim levels.It appears a Sierra from 69 thru 71 was an option package available, even a base model, that gave you the custom comfort and appearance group, chrome front bumper, inside mirror, chrome hubcaps and lower side mouldings. The Sierra Grande from 69 thru 71 was the super custom trim level package with everything the Sierra came with except the lower mouldings were swapped out with door edge guards. Remember, these are the minimums, seperate options could always have been added when ordering any trim level truck up at the dealership.
