What I posted last week when this question was asked in the Blazer/Jimmy section:

'68 Chevy and '68-72 GMC fenders are all the same and are identical to the '67 fenders except that they do have side marker light holes.

'69-72 Chevy fenders are about 2" shorter than the fenders described above to match the length of the later more blunt front hood.

'69-72 GMCs use a large trim piece riveted to the top of the grill that sits in front of the hood to fill the gap caused by using the shorter later hood and the longer earlier fenders.

'67 GMC grills have the letters G-M-C embossed into the center of the grill. The vertical and horizonal bars cross in the same plane in the center to form a mild intersecting point.

'68-70 GMC grills are the same as '67 grills without the embossing.

'71-72 GMC grills have a stylised embossing in the vertical bar and the horizonal bar is in a backset plane from the vertical.

'67-68 GMC grills have a small trim piece riveted to the top of the grill that sits under the longer "slant nose" '67-68 hood.

'69-72 GMC grills have a large trim piece riveted to the top of the grill that sits in front of the shorter "blunt nose" '69-72 hood.

'67-68 GMCs and Chevys have a bumper filler panel that goes between the core support and under top edge of the bumper. The panel was simply eliminated in later '69-72 trucks.

There are slight differences between core supports between years and of coarse GMC 4 lamp core supports are different from Chevy 2 lamp core supports, though all the GMC core supports are essentially interchangable with a hole or two missing or extra between years. The missing or extra holes corospond to the hood/grill combinations and whether the bumper filler panel is present or absent. Hood latches are also specific to hood type.

Special-K may very well be right about all GMC latches interchanging though all the years are not identical.
