I'm going Toyota axles for a number of reasons, if you aren't committed yet, it may be worth a look.
56 inch WMS to WMS 4.10, 4.33, 4.56 and even 88s from the factory 6 lug chevy (good for me-I have a set of MT with 37.5 swampers) Extremely strong-axles as big as a 60 SOA from the factory so pinion is at a better pitch Close knuckle birfield (?) joints Crossover style steering Good aftermarket support-although not needed Availability of factory rear disc
Only problem I haven't answered yet is normal (by my standards) yokes.
