cylinders on a Tracker?

I have a `93 Geo Tracker that is already bagged. I'm not totally satisfied with the setup in front and so we're thinking about redoing it with cylinders where the struts go. Has anybody done or seen this? Does anyone know of a kit for the front. We were kinda leaning towards a 4" cylinder and using universal brackets for the top and making brackets for the bottom. Anybody forsee any problems doing this, or have suggestions for a better setup? I'm wanting to redo it, because the bag setup doesn't quite let it lay out, and I really want to set this mother on the ground! Thanx, everyone!
