Hi Chick,
  Your hinge assembly looks more light gray than mine. Is yours oiled or dry? Mine is oiled and it turned (over time) from that gray like yours to a darker gray in the photo, which matches the hue of the spring on my car when viewed with the eye. The camera shows otherwise and that is likely due to the round shape of the spring reflecting the flashes light in a diverging pattern whereby the flatter shapes of the hinge reflect it back more to the lens (astrophotography is my passion so I'm familiar with light behavior)
  If you ever parkerize a firearm (it is the same as phosphating) they too tend to darken over time when oiled. It is likely the oil causing that reaction. Thanks for the reply!

Lower the hood enough to insert washers between the springs. Raise the hood and it should have enough slack to pull out.

Scott,

  What are you talking about?  The picture speaks for itself in regards to hue between the spring and hinge. Looking at it in person they look the same. The photo shows a slight variance.

Mike
I've noticed different hues when comparing spring steel and non spring steel. That is all. Photorealistic airbrushing is a field with which I am familiar.

You do not need to use washers. 
Every make and model I've done was accomplished with a vise and a hook to remove and install the spring.  Piece of cake. No washers.

I parkerized my hood hinges along with the hood latch and some other underhood parts about 7 years ago, and the finish is still holding up and I am not too far from ocean.

GM Part number?
The GM P/N is 3848372 and I paid $30 for the pair.
It is a 28 coil spring.

It doesn't look like that part number is good anymore.  I did find #3848272 which is also a 28 coil spring for $14.62 each.  I hope it's the same one.  There are also some springs listed on ebabe with the same 3848272 part # which allegedly also fit Impala, Camaro, Chevelle and Firebird.

The GM part number is 3848272. I have them in stock. And yes they are used on multiple makes and models. I deal with HoodHingeRepair. Willie has rebuilt countless hood and door hinges for me. Not to mention repairing damaged hard to find hood latches for certain models.

Has anyone been able to find, source the hood springs for the ZL2 Cold Air Hood? The original GM Part # is 3877203.
