The Stovebolt Site Forums The Shop Area Paint and Body Shop AD hood hinge bolt questions

What type of fastener is used on the hood spring bracket to firewall on the ’47? My ’47 has a partial threaded 3/8” bolt and two nuts. The shop manual for ’48 to ’51 looks like a rivet. The FAM for ’54 shows the tapped disc spot welded in place. What do you have on your truck?

The hinges on my ’47 have only 3/8” holes. I purchased the shoulder bolt kit for ’47-’55 that has two bolts with 3/8” shoulder and four bolts with 7/16” shoulder. That’s only 6 bolts, so they’re for attaching to the hood and not for the other end of the spring bracket. I did find a vendor that has individual shoulder bolts so I could order four more with the 3/8” shoulder. This brings up another question, when did the hood hinge go from all 3/8” holes to 2) 3/8” and 4) 7/16”?

The shoulder bolts are 5/16-24. I removed my hood and found 5/16-18 bolts as the body shop had tapped out the holes in the hood and used their shop stock bolts. I haven’t found my original bolts so I don’t know what was in there. Are all the hoods from ’47 to ’55 5/16-24?

I couldn’t find 5/16-18 bolts with 3/8” shoulder so I made some for the tapped out hood. I just spent this morning searching for similar questions here and found Phil did the same thing: https://www.stovebolt.com/ubbthread...true/hood-hinge-bolting.html#Post1385569

On my ‘52, the bottom is riveted with a solid rivet that has a shoulder on it to give the clearance needed to operate smoothly. The top has a shoulder bolt with a captured nut on the back side. The first picture is the bottom and the second is the top.

If you have a lathe or know a buddy that does, they are easily made.

My '51 has the same arrangement as Phil's.
The pivot point where the spring connects is also staked (riveted) in place.
