4.77s were usually on 89 RS Troopers, and some LWB 1st gen Troopers with the "Big Tire" option package. They also came on one or two other oddball models, I don't recall which though.


The '89 RS (2-dr SWB) is the most definitive answer as to lcoating 4.77s... The model is rare, but all of them had the covented 4.77s. Beyond that, there are more oddball years/models, but the criteria is often debated. You'll have a hard time searching for a staight answer on definitively locating those.
