However, although a full floating 9-inch would be the ultimate, you'd better be ready to drop some serious coin because you're talking all out racing axle now.
IMO, run the 70 until it blows to pieces or you want to shead weight, then get serious.
ive used full floating 9 inches in alot of race cars.....Warn also used to make a kit for them too.....if i looked around i could find a full float kit fairly cheap......
