521 hood fix Anyone?

[521Lvr]

so my hood bars are all unglued and the side bumpers are worn out.

Now when I'm going down the highway my hood shakes pretty bad.

I figure most all of us 520/521 guys are dealing with this or figured out a good fix.

What do you guys think?

My 71's hood was like that so i swapped it out :D But why not just weld in a few tacks on the supports?

I took the hood off, turn it over, put a little weight (bout 10lbs.) on the braces. Then ran a bead of silicone coulk along the braces, both sides. Let it set over night and it's held for years. You can get the bumpers on EB or Datsun Restorations.

the forward bumpers are different than the rear bumpers. forward are square and rear are triangle. the set of 4 triangle on ebay are for the rears only but i guess will work for the forwards but are not correct.

I just found some niffty little adjustable bumpers from an early 90's Mercedes at the junk yard the other day. Maybe a 190E or something. I was going to use them for exactly the same problem you describe. They are basically small screws, maybe 1/8 inch in diameter, with a rubber button on the top. Just drill two small holes in the front corners of the core support, and put the supplied nuts on both sides, adjust, and your done.

I would go get a tube of body seam caulking and re-glue the hood braces back into place. I would squirt the body seam sealer into the correct ares and then close the hood so it does not dry with the hood a little crooked or tilted.

sorry Pac, but I'd stay away from the tack welds.....the metal will flex just enough to cause it to crack in time.

 

They also make a panel adhesive for glue in patch panels. I think the seam sealer would be the easiest to get ahold of and should work fine.

I also added a bumper stop (1/4-20 or 6mm threaded stud) from some car (who knows where they came from), on both sides near the front. I just drilled a hole and tacked a nut (welder required but jb might work) on. This way I could adjust them so hood matched fenders. This did more to keep the hood from shaking then anything else.

I had the same problem on my 620. I used seam sealer as I believe that this is what was used in factory. Have not had a problem in the two years since.
