I have a 51 Fleetline and the drivers side of the hood will not go all the way down when I shut it. I have to push the rear of the hood down to get it to align. I am sure the bolts are not the correct shoulder bolts, but I have read where the springs are different from what the repo parts houses are selling as correct. It has the 28 coil springs in it now and I read here that Chevy recommended the heavier 53-54 springs. Is this true or do I have other issues?

Unless the coils are binding in the hood spring preventing full closure, you have hinge attachment points binding or misaligned, tough to diagnose from here.

The 49-52 Chevrolets used the 28 coil springs. The 53-54 had the 23 coil springs. My 1961 Master Parts Catalog specifies 23 coil springs across the board; 49-54.

My suggestion would be to start with replacing with the correct shouldered bolts and see what that does. Next replace with fresh springs. If that still does not remedy the situation, then an inspection of the hinges to include where the hinges mount to the cowl would be in order to see if the hinges or cowl is bent in any way. After that, a complete realignment of the hood which would require adjusting the position of the hinges.

I also own a 51 Fleetline. After fighting with trying to get the hood to stay up and changing the springs, I went to the junk yard and for $5, bought a prop rod. I'm happy. bobt

Thanks, those pictures help a bunch and I was wondering what the differences were between the two springs. The springs in it now are newer and the hood drops a fair amount when you open it, but it is aligned well when it is completely shut. Going to try the correct shoulder bolts and go from there.
