I'm sick of baby sitting toyota axles every time I go out so I'm finally stepping up to man axles but I've never messed with them and don't really know where to start. I'd like to get a 60/14bolt set with 4;56s but the set on here is pretty far away and YJ60 hasn't called me back yet

In the mean time I can get a stock set of 60s with 4;10s and drive flanges. They are from an 80s dodge 350. So what needs to be done to them to make them last with 39-42" tires and a V6-V8?
