I've taken my hinges off, and they were very worn, but I was able to pound the rivets back tight again. So that works much better.
But it still sticks way way up in the back of the hood. You know, it almost looks as if the hinges are not from this truck, because the arms that attach to the hood seem almost an inch too long. I'll bet I could shorten those without any problem at all.
It doesn't make sense to me though. Those hinges were designed to close the hood tight, and they physically seem to be too long to be able to possibly do it.
Any ideas why this might be happening? Being a GMC 3/4 ton, there's virtually no parts available for it unless they perhaps cross-reference to the more popular Chevy. | | | | | Joined: Aug 2005 Posts: 6,377 Ex Hall Monitor | | Ex Hall Monitor Joined: Aug 2005 Posts: 6,377 | Try pushing the back of the hood down after it's closed. If it goes down try oiling the hinge pivot points and work it up & down a few times. Hinges will often work that way when the pivot points are dry. Another thought is you may have overtightened things a bit when you snugged up the rivets. Did the back go down alright before you tightened the hinge rivets?

I almost made the decision to get rid of the hinges and just hood pin it down, except that I really want the hinge system to work like it's supposed to.
I know this is a Frankenstein truck, made from at least 4 other donors to make one good truck. I would not be surprised if half ton hinges are actually different from 3/4 ton hinges, and maybe that's what I've got. That's a thought. Are they different? | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | HotRodDad...there should be tons of info on this Maybe scan a few days back on the posts.
From memory I think your to put a piece of 2x4 under the front of the hood and, while the hinges are loose, push down on the back of the hood. This usually takes 3 people from what I read. Two pushing down and one tightening up....
Hey, it may even be a tech tip now. I just have not looked recently....but I'm coming to that point on my truck to. | | | | | Joined: Mar 2005 Posts: 1,513 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 1,513 |

Yes, the procedure that Curt B. refers to in the post above works very well. Thank you, Mac Kinghorn.
