My 94 had the dual sunvisors on it (I don't remember seeing them on later trucks). As mentioned (along with the other items), the serpentine belt, pulleys, and idlers (tensioner too) were all different with the 7-rib belt. They also had the "staked" oil cooler/filter header adapter. They also used the OBD port under the hood with very limited diagnostics (until they were reflashed to later PCM programming). They had the UVCHs with the "plastic latches" instead of the "bail wire" clips and they had oil seals on them as well. The clutch master and slaves had smaller bores on them and the slaves were prone to cracking at the line boss. I'll probably remember more weirdness later. Cheers!
