John, you can use either a MII suspension setup on the front, or a straight axle with buggy spring. Lots of manufacturers for either type of suspension. Not sure about the width of the chevy rear end. I do know an 8" Ford Maverick rear end is very close on the correct width. There are a couple of manufacturers, Moser and Currie are probably two of the more well known, who will narrow a rear end and make the axles to any width you require.
