There are only two different coil thicknesses available. Eagles used the thinner coil springs. A 1970 Javelin will have a thicker spring. Then there are very slight, arguably negligible, differences in spring length that account for slight differences in weight. That's in contrast to other companies who would vary spring rate, AMC only changed spring length. Cruising through Rockauto you won't see springs listed, since technically Eagle springs arn't sold. This is because the factory used slightly different springs on each side to account for the engine offset.
1970 Javelin Springs will likely put your station wagon just as high as you want it. Eagles can actually accept any size tire if you are willing to modify the fender opening or make a minor cut to the rocker panel. With the fender off the tire doesn't come any where near the frame even with 33x12.5 tires.
I personally use 235/75 R15 tires on all my Eagles. My Red SX4 in this picture has those tires, although I don't have a picture from before when the plastic fender flares were on it. It looked alot better then. The fender flares don't need any external modifications, they just need their 4 inch depth inside the wheelwell to be narrowed to about an inch. A formal lift wasn't at all necessary, in this picture the rear springs are replaced and stiffened but still the original height and the front springs have yet to be replaced.
There is a projection of the rocker panel that needs to be trimmed back, but it is a minor cut. With the fender on you just continue the curve of the fender down through the rocker panel. The part that gets trimmed is then only about an inch of rocker panel, and that inch doesn't effect the strength of the rocker panel or even open a sizeable hole in the end. The second picture shows this projection's odd shape and it should be obvious that cutting it back doesn't effect much.
