I remember looking at a site a while ago that listed springs for just about everyhing you could think of, and now I can't find it. I'm looking for springs to drop the back of the wagon a bit, and can't find anywhere else that lists the parts specifically for a wagon.

Look in the back of a Moog book, or see if you can find the listings online somewhere. Use the equation for a spring to determine the new installed height.

The rear of a wagon is too heavy to work with an F body spring. Always do the math. The back of the spring book provides all of the specs where you can calculate the compressed height of the spring. Remember F=kx, where F is the force (or weight) on the spring, k is the spring constant, and x is the the amount the spring is compressed due to F.

Using the specs for a stock spring, you can calculate F and then determine the compressed height when using another spring.

I had my buddies A-body 71 chevelle springs in my wagon for a few yrs. when I bought wagon springs last yr it raised my car 1-1 1/4" in the rear which I needed since I decided to switch to a 30" tall tire instead of the 28's I was running. They worked great and after further research at my local "old school" parts store, u know the ones that have guys who actually work on cars(unlike autozone or advance) I found that the spring rates were near the same when I looked them up and compared the two in the moog book.

Here are the Moog specs:

The stock wagon replacement spring is Moog 5391. Use those specs as a reference and calculate the correct spring based upon the change in ride height you want.

Using the equation "load=(free height-install height)*spring rate" I got "install height=free height-(load/spring rate)"

Does that look right, or do I need to take wire diameter and spring diameter into account somewhere?

The wire diameter and number of turns is what makes up the spring rate, so you don't need to account for them again.

Yes, "load=(free height-install height)*spring rate" is correct.
"install height=free height-(load/spring rate)" is also correct.
