I kinda learned it be accident. I needed to get the back of my old '65 Chevelle convert up for tire clearance. Put Station wagon coils in the back, did not hook nearly as well. Too young & dumb to test with them first. Hauled it to a race, to find out the expensive way. I learned longer coils was the correct way to raise it. That right air bag needs the least air that keeps that corner up. Had to run one of those in that '65 Malibu too. Only thing I ever raced with coils on all 4 corners. 7" tire, no prep days. Seems like it was some Rambler springs I found, same dia, but longer, wound from slightly smaller wire raised it an inch, and hooked better than ever.
Had a local salvage with a big crate full of pairs of coil springs tied together, tagged with what they came from. Bring a tape measure and calipers.
