They will work just fine, agreed I'd go with later model units.

I'm not sure why everyone is so crazy over the Sal. rear. Upgrade a RRC/D1 rear axle with heavy duty shafts and you're good to go, plus you're not giving up as much ground clearance.

Unless you're going big, with tires and horsepower( which destroy other things as well), the RRC/D1 rear axle is fine.
