Long story short: 1977 Caprice wagon (sig...). Back end is sagging and I'd like to replace the springs, but I was thinking maybe it'd be simple to throw bags in there instead? It's got coil springs not leafs, to a WTF-link type thingy... lol. Lemme get some shots when it's light out for ya'll. Thinking maybe there's a possiblilty somebody's dealt with it before. Thx!
