Well I went and looked at the 1991 Jimmy and came back confused.
The parts are in good condition but not what I expected.
The front grille is I guess from a base model and is painted silver and uses a single large rectangular headlight on each side with lower marker lights and in this case it was actually a Chevy grille with the bowtie. Looked alot like the grille on the 94 Chev work van that I drive. The fenders are in great shape, rad support has some scale on it, the bumper was straight but had some chrome bubbling/rust at drivers lower side about the size of a silver dollar.
He doesn't want to give the wiring harness as he wants to keep it with the engine and frame to adapt to the 1937 Ford truck he is building.
Are there several different grilles in 91 and are the rad supports all the same?
Thanks
Found picture of a 91 burb with the same grille
