I've searched up & down the threads, but I'm not quite finding what I'm looking for. Anyone that has done the replacement coils for a front lift, which did you use, I've read that the 70 Javelin is a good donor, but there seem to be 3 different heights, and it seems to be 5 ltr (304ci I think) with & without air and 360 with & without air, the 5ltr with air seems to be the same spring as the 360 without, but that still gives 3 choices and each step is like 3/4" longer free height, that could be 1-1.5" more lift per step.
So I'm trying to get a better handle on which is my best candidate based on what others have used, and how much lift you got.
I bought a set for a Concord wagon with 304 and AC but I haven't had time to test them yet.
I got the Espo springs and things coils for my car and I swear it brought the car up 1.5 inches. I had my rear leaf springs built with 1.5" of lift and after the new coils installed the car sat level and not 1.5 higher in the back.

The last couple of days I have been researching a way to get a little more lift on my wagon since I lost an inch after installing the winch bumper. I guess it was known, I didn't know till yesterday, that ESPO sells Javelin springs as Eagle springs. According to captspillane in another thread, Eagles had a smaller diameter wire than Javelins for the spring. Which would explain why the front is higher when using an ESPO spring.

I'm gonna give www.coilsprings.com a call in the next few days and see if they have an option for me. I have a 1/2" spacer and could just replace it with a 1" spacer to get the inch back, but would rather not.
