Title: Hood Hinge Repair
Post by: Brian Conway on March 31, 2015, 10:55:05 PM
     The right side hood hinge on my 69 seems to be buckeling.  The lower/forward rivet seems to be pulling away from the fender wall bracket.  Allowing the hinge arm to lean inward.  Is this a simple repair ?  Brian

Mine were ok, but as a precaution i added nuts to the wheel well side for strength. You could add some weld to it, grind down and no one would know or care. I had the same problem with 65 fastback, but had to weld a new socket nut(?), different design than my 70, same principle.

I would go and replace the hood hinge.  Thats probably the easiest repair to do here....

Thanks Marcus for the reply and suggestion.  So the after market hood hinges are less than a $100 a pair with springs and bolts.  Ebay has original/used for less than that.  I am reluctant to buy after market for all the obvious reasons.  Used are subject to failure at anytime so what to do ?  Anyone with a recent experience ? Suggestions ?  Thanks for the help.

didnt realize it was the hinge that was the problem, sorry. I purchased a set of original hinges because someone oblonged the holes in the originals, not because they didnt work. I will shut up now.

Well....you know what I am going to say here already.  Your better off getting some nice originals and using them.  Getting a nice clean set that is not damaged could be a bit of challenge, but they are out there.  You have a good car Brian, so would like to see you keep original parts on there.

What's the cap on the end of the spring coil? Is that a factory piece?

Thanks for the advice.  As this is one of the problems common to all of our cars I was thinking someone had a sure-fire resto already figured out.  The vacuum cap on the hinge spring is NOT OE.  After having torn a couple of shirts and having drawn blood more than once I like to de-fang these little annoyances.  The battery ' J ' bolts are another vac. cap recipient.  Brian

Good idea. Beats having to clean blood off the inner fender!

     I am revisiting this post to ask which phosphate (manganese?) to use to get the desired oil/phosphate finish on the 69 Metuchen hood hinges ?  Will the shock tower caps and the coil bracket be the same O/P finish ?  The hood/hinge bolts are which finish ?  The coil bracket bolt finish ?   Thanks,  Brian

Anyone know a place that can repair the hinges?  My 65 F is doing the same thing.  I much rather try and use my original one because of the date stamp is visible on the driver side hinge

Somehow I missed this - I use Electrochemical Products E-Phos 630 http://www.epi.com/p/other-misc/phosphates/manganese/ephos-630 I got mine thru the business that does my zinc plating. I got some other phosphating chemicals from Amazon. To get different shades of finish, I vary the amount of phosphoric acid, usually less, in the "bath" and use different amounts of time as well on hinges, shock towers and coil brackets (I paint my 65-66 semi-gloss black - I have a sample). To get a dark finish on the springs, Eastwood Metal Blackening solution (not the kit, just the metal black). As always, proper preparation is required. On the hinges, I spay WD-40 on the pivot points until is runs clear. Use a whole can if necessary. Save the "drippings" to use as a dip or put into a spray bottle.

You might try a shop with a 20 ton press.

Doing a search on hood hinge repair.  My drivers side hinge has a fair amount of play in it when opening the hood. I have a OE used set coming in the mail today from WCC.  I am trying to find if their is a recommended party for rebuilding the hood hinge for smooth operation.  Thinking I would recondition the OE one coming in and send my date correct originals off for rebuilding.  Anyone know of a contact to rebuild hood hinges?  Thank you, Brian

I have seen refurbished hood hinges advertised. Not sure of the years but 69 Mustang iirc was one. You might check with Rare Parts to see tbey repair/rebuild them.

I would try penning the rivet to take up the slack. I use a air chisel /hammer with the appropriate rivet tool attachment. That many times dose the trick. The companies that restore the hinges are not inexpensive plus if you are concerned about originality the rivets they typically use are not the same as the ones on your factory hinges. If you are not concerned about date codes you can buy about 4 pairs of nice used ones for the price of the rebuild charge.

The tools I used with excellent results.  Some of the positioning is a bit awkward so the vise and another heavy hammer suffice for backing.  The cold chisel ground to the rivet groove size and another hammer to do the whacking and works just fine.  Brian

OK, my mistake on jumping into the wrong thread stream for my question.  These hinges are for my 72 and not a 69 or 70.  My apologies if I miss spoke, but I think the samer guidance may work to repeen the rivets.  As I do want to keep the originality and not go with a different rivet style I will give that a shot.  If nothing else I can test on the used set I am getting before attempting on my originals.  Thank you all.

I have no first hand knowledge for these guys. Chevy stuff, but still, they might could do it.
