79 k5 Blazer center hood stop
« on: April 07, 2020, 05:09:53 PM »
I have looked everywhere for one of these and can't find one. It bolts on the firewall at the top of the tunnel and is suppose to keep the hood from drooping in the center. They came mostly on 79 and may have been on the 77 and 78 K5 and c10 truck. It mounts using three bolts. Any help would be greatly appreciated. Thanks Norm

I don't believe that part is available as a reproduction item, although I can't admit to specifically looking. Junkyards or as a "want to buy" on one of the forums will be the best sources I think.

But if you can't source one, don't despair. It doesn't perform the anti-droop task you think it does - it existed as a passive stop to anchor the hood to prevent it being forced backwards from a head-on collision. I'm not certain when it first appeared, but I have two 1978's ready at hand and one has it and the other does not (perhaps a mid-year change?). The one that does not have it has survived fined for over 40+ years without any hood sagging.

I'm trying to think of a center support anti-droop support bolted to the firewall....

Thanks, I was thinking it was a mid year in 78. I see more pictures of 79 with them. I am just checking around it more a cosmetic thing, but I know why it was put there. I know they change the hood in 80 and it went away. Thanks Norm

I’ve seen em
I think it was to keep the hood from going back through the windshield in a collision

Those are on the ends at the cowl and do not match his description. I have no idea what he is talking about. Pix would help.

I looked under the hood of the 79 in my driveway and saw nothing that matched so I looked through publications and saw this for cab and chassis

So looks like an option for K5, Suburban and 30/35 series cab and chassis.

So is it anti sag or anti decapitation?

I'm going to assume since this is designed to help make the hood a little more robust and not vibrate as much as they did. The two anchors on the cowl were there to stop the hood from decapitation. This is like a bump stop and plate like at the front corners of the hood.

Of course, it would be helpful if someone had more pix or detail to establish an absolute reason for its existence. Please contribute if you can.
