71 to 67-68 hood conversion

[jhyder408]

so I've been reading up on this on some other threads. but I still don't get how the hood would be longer on the 68 than the 71. the fenders are the same, the cowl is the same.
is the latch different?
everything seems to be in the same place.
anyone have an explanation?????

[short-t]

Fenders are not the same!

The leading edge Of the fenders for grill surround which aligns with the hood is different

67-68 chevy fenders fit chevy 67- 68 but fit GMC 67-72. So to convert a 69 -72 to a 67-68 you need complete clip ie fenders, rad support and hood

SO, to put on a 67-68 chevy hood on a 71 GMC, i really just need the core support out of the 67-68 because the fenders are the same? did i get that right?
The goal here is to put a 1967 or 68 hood on a 1971 GMC. He wants the slope nose.

All the GMC fenders are the same, you need a hood, a hood latch and a trim piece for the top of the grill, and I'm not even certain you really need the hood latch. First pick is a painted 67 grill (slant nose) and a chrome 70 grill (blunt nose) notice the difference in the size of the trim piece on the tops of the grills. The trim pieces are riveted onto the grill. The 70 (and all 69-72 GMCs) use that big chunky trim piece to "add" the extra length to the blunt nose, mimicking a longer hood, the 67-68s simply fill the gap from the top of the grill to the bottom of the hood. The 2nd pic is a 67-68 cowl hood on a '70 Jimmy with the original hood on the roof.

Also note the 67-70 GMC grills are all the same, except for the "GMC" embossing on the 67, the 71-72 grills have the painted recess. I do not know for sure if the 67-68 trim piece will fit those grills.

The hood latches interchange an all GMCs. There's 67/68 and 69-72. The 67/68s have a sloped front just like the hood,but a '69-up still works.

In '68 when the hoods went more blunt the overall length got shorter. On both Chevys and GMCs a grille surround was used to compensate. On GMC the surround is 3pc...fenders and hood. The fender surround pcs. slip over the same fender. The center pc is what makes up the difference in length for the shorter hood and fills between the grille and hood. In 67/68 there was a body piece used between the grille and hood.

Sorry to bring this to the top again, but has anyone else had any experience in putting a 67-68 hood on a 69-72 GMC?

From what I gather from the posts above you can directly put a 67-68 hood on a 69-72 GMC by basically just removing the division bar above the grill. The 69-72 GMC latch will work for a 67-68 hood.

Does this sound correct?

Thank you,

Awesome information.

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.
