How hard is it to replace hood hinges?

On my '70 "S" . I've got lots of mechanical experience but none aligning body panels. I'm looking at some US re-manufactured hinges with springs on ebay Any help would be appreciated!

May I ask why. The hood on my 69 H/O drove me crazy and would not stay up. After I asked every H/O owner I could find if the scoop weight caused them a problem and fretted for about a year and looked at all the hinges out there I finally just crimped the ones I had a tad and they worked fine.

They are pretty straight forward to replace but a strong friend is pretty much a must. Have said friend hold the rear part by the windshield & in front of the hinge as you remove the bolts from the hood & fender & then install new hinge.As far as aligning them, it is best learned by experience. After you attach the new hinges, SLOWLY lower the hood, frequently checking both sides, especially at the rear of the hood to see how it fits the fenders. Make changes in small increments & you might need some shims between the hinge & the hood. Again, SLOWLY lower & raise the hood to avoid scratches, chips, & cursing.

Mainly because the left one is pretty bent.........the right one is too but not as bad. Car has a good number of front end wrecks in it's history. the hood is WAY right and over the fenders when open

I installed my hood completely by myself with the exception of initially placing it across the open engine compartment


Raise the hood in a garage or somewhere you can tie off the nose with a rope in the "up" position. Mark the location of the hinge on the fender and hood. Then block the hood at the open position at the base on each side, inboard of the hinge, with something like Styrofoam. Unbolt and replace each hinge, one side at a time. Then I'm sure you'll have to move it slightly to align it properly, again using the Styrofoam and rope to hold it in place.

This method would probably work well for me, as second set of hands is something I might not have.........and I could easily tie the hood up where she sits in the garage! Sourcing some big blocks of Styrofoam my be a little harder, but not impossible Thanks!

Just curious, why wouldn't you just unbolt the tongue on the 70 so it's out of the way and doesn't get damaged if you're playing with hood alignment?

Well I hadn't thought of that actually. Does it have a good chance of getting damaged during the alignment process?

I don't think so. It has 3 bolts that hold it in a fixed position.

It sounds so easy. Just unbolt it.

In MI, unless the car has been restored or is from out of state, "unbolting" the hood tongue goes like this: the bolts are rusted to the J nuts, so the whole thing turns. This removes a large chunk of the hood tooth which is pot metal and not easy to fix.

It's a Wisconsin car so yeah this has already happened.........there's like 3 different sized washers managing to hold it on at the moment

I'm gonna be pulling the trigger on these hinges today so I'll let you guys know how it went in a few weeks. Hopefully I'll be able to post a pic of the hood staying up!
