Vikki, I also use the 5/8 rod method. I double nut the bottom with heavy washers, run a single nut down to the upper shock mount with doubled oiled washers under it, and double nut the top about 6-8" above the shock mount. I can put a wrench on the shock mount single nut to hold it and a socket on the top doubled nut to turn it. The oiled nut and washers work great and the only time I get under is to take off the bottom nuts. In essence I'm pulling the lower arm up from the top.
But, I found out on this last spring cut I no longer need the rod to remove them, not enough free length left in the spring.
