Yeah, yeah, yeah...get an Explorer axle and modify it!
Well, some of us aren't welders and don't want to pay someone $1k to modify one. :D
Meanwhile, an SN95 Mustang axles are plentiful in junk yards, have almost exactly the same width as a B-Body 8.75" and will come with limited slip and disks....and they can be had for $250ish plus the cost of welding just the spring perches. A vastly simpler and cheaper way to go.
The biggest drawback is that these evidentially have 28 spline axles (unlike the 31 spline Explorer units?) so they're supposed to be a bit weaker.
How much weaker? Why aren't more guys going this route? Yes, I suspect there's a reason.
Thanks for an input.
