Thanks but none of those pertain to my request...no coil bind, no yellow spring, and no 1.780" pressure. I saw those specifics previously so that is why I posted.

I just checked a set last Wednesday, and wrote down all the pressure. I can't find it though. I do remember that I could have shimmed them .030" with a .560" lift cam and still had .050" to coil bind, but spring pressure only went up a little bit.
I'd recommend just installing them dropped in. If they don't provide enough pressure like that, upgrade to a better spring.
The only went up like 6lbs on the seat or something really low... Sorry I don't have it, and yes these were the yellow springs.
What are you trying to use them for?

seat pressure 90lbs @ 1.8" installed height
max lift .570"
open pressure 280 lbs @ 1.25"
coil bind 1.160"
This info is for GM part # 12499224, which is a yellow spring that came in the 04' Z06.
The springs come individually wrapped and are made in Germany. The part number I provided is for a set of 16 springs that run about $54.
