On the bracket, typically clear zinc, I have seen some phosphated service parts

I'm guessing the spring was designed for use with the Autolite carb and not changed or updated if the Holley carburetor was used.

On the subject of '68 302 4v, does the angle vary with the intake?

The one I took off of mine, 1) did have a green spring 2) matches the color of the grey bracket posted 3) is at 90° 4) was on the iron 4v manifold with the Autolite carb

Assembly manual lists green spring for stick and blue for automatic, however I've taken off a bunch of originals both transmissions and only ever seen green

The green spring is 20 coils, 1 inch long (w/o hooks) about 1 7/8" overall and approximately 9/16" diameter

I would appreciate confirmation from anyone with a green oem spring or info on the blue spring

Why do you have to tell everyone??  ;) 

I checked the 1968 MPC and there is not a spring with those measurements. The closest one is the C8ZZ-9737-B, but it is different.

I found a photo of the spring that I had snapped several mos ago.  I count 20 coils as well.  I had painted the spring light blue based on what I thought was correct information at the time.  Unfortunately I don't have a "before" photo.

And you maybe correct...

That is the spring, noticeable by the offset hooks.

I have several photos of originals but its hard to determine the color

I am accepting of blue or green at this point until we find more information

That's what I was thinking about the color, i.e., is it blue or green.  I agree that for lack of a better description that it is acceptable to call that green but since the blue is so rare, does it really exist or did a color blind person enter that spring as blue in the parts description?

Worse yet, who makes the right matching color paint now?

...and I'm not counting coils. I can't count that high.

The question is why hasn't anyone yet read this post and posted a pic of their original spring? I find it hard to believe with all the SAAC members here on the forum nobody with an original spring on their car hasn't posted a pic yet. Gary
