like ogre says, check the height to your bump stops, ride height and go from there.
what is the 8.8 from? how much width difference? I put an '99 explorer 8.8 under a 57 and it fit pretty good. I used welder's series brackets and rods, some modified, fabbed up some frame brackets and stanchions to attach the 4 leaf. used a stabilizer bar from a ford ranger (some have the 8.8).
just be careful not to overheat the axle tubes when welding on a new set of spring pads (you can get spring pads from a trailer supply shop). there is also a normal style yoke available for the 8.8 if you wanted a chevy style ujoint back there. can't remember what the yoke is from but a driveline shop could probably fix you up.or see below.
I included a couple of pics of my set up so you can see the ranger stabilizer bar if youre interested in that stuff. there are small ones and larger diameter ones from their sport series trucks. this is a small one because thats what I found that day at the wrecker.
some ideas for yokes, if interested
