A little background first:

I put my 68 chassis together many years ago, & at the time I ordered new coil springs front/rear I believe from a company called "coil spring specialists"? (I need to see if I can find the receipt) Anyway, they asked very specific questions to get me the right springs. Well, upon first installing them they seemed crazy stiff, in fact the upper control arms stayed on the bump stops. A couple years later I had the car all together for a mock up as I was fitting body panels, etc. The car still sat like a 4X4 front & back. It looked like it had no engine installed.
I then called the spring manufacturer & they assured me I had the correct springs & they just needed to settle down. I get that, they do settle over time. But, it never did. At one point I threw several hundred lbs of sand blasting material on the floors to simulate the interior as that's all that was missing from a weight perspective. no change. Then I put rachet straps on the suspension while it sat on a 4-post lift & pulled it down lower than where it should sit. Left it like that for several weeks. Released the straps & it bounced back up to truck level. So something was for sure wrong with these springs.

So back to my question.

I have the suspension all apart again & I was going to cut a few loops out of the springs to get the car to drop. But I am unsure if I should do that, or just buy more springs & hope to find something that works. I would rather have the car sit a smudge low than too high. Just a personal preference.

Anyway to figure out what the heck these springs are by thickness, height, etc?
I am lost.......

I went ahead and cut one coil off each frt. coil, it is fine by me. right height and the ride is not over bearing like a 4x4 works for me.
