9s are good, but take a little work to get them where you would want em... obviously the late 70s F trucks from ford are a great source of 60s, as the broncos have hp44s and 9s... Scout and Grand Wagoneers have the 44s front and rear in most cases, and I believe some of the old FSJs have some pretty stout axles... I say go with tried and true and search for some dana 60s, kingpin in the front if you can find it, enlarge for 35 spline shafts, and go... the 80s model F250s and 350s I think also have 60s in the front, but they are ball joint instead of kingpin, and have a sterling 10.25 in the rear... It's also a pretty stout axle, but has less aftermarket presence
