[1969 GMC]

GMC had the Sierra (better) and Sierra Grande (best) from 70-72. The Fender emblems said 'Sierra' or 'Sierra Grande' as well as the special emblem on the bed in front of the rear marker light. This is also where the Longhorn emblem appeared on Chevy trucks.

Chevy had CST from 67-70 on trucks as top of the line. Blazers had it from 69-72 as top of the line. In 71 for the trucks, it switched to Cheyenne (better) and Cheyenne Super (best). For some odd reason, Suburbans could never get the top of the line trim.

Also available were the Custom, and Custom Deluxe (kind of like a mid level, between plain C/10 and Cheyenne/10). Then there are the Custom & Custom camper emblems that were above the door handle. Chevy and GMC both used these.

Then there are GMC fender emblems...almost too many to list! 1500, 1500 V-Six, 1500 V-Eight, 1500 Custom, 1500 Sierra, 1500 Sierra Grande, Jimmy, and there are probably more I am forgetting (in addition to the 2500 and 3500 series).

Also can't forget the engine displacement emblems. 292 (69 and 70 only). 8-350, 8-396, 8-400.
The Four Wheel Drive emblem that is on some 4x4's under the front marker light.
phew
