I'd personally run a Dana 60 because 1. That 4runner is a heavy rig and 2. Isn't that runner the opposite drop of a mini truck axle?

A Jeep Wagoneer D44 is typically what is used to get it done as cheap as possible. The diff drop is on the correct side. the width is about the same, and they had the same bolt pattern as the Toyota.
I've never built a 3rd gen 4Runner, but keep in mind that 1996 and newer 4Runners have a wider body than their 1984-1995 counterparts. For reference, your 1986 rear axle measures 58.5" wide compared to the rear axle under the 1999 4Runner which is closer to 60". You'd need to run some wheel spacers just to get back to factory width, and if you want to go even wider, which is important for a full body 4Runner wheeled near trees, you'll be exposing more and more of your drum brakes with increasingly wider wheel spacers.The issue is even worse for the front end. Two main reasons are 1) the 1979-85 live axle measures 55.5" wide compared to your 4Runner's front IFS width of probably closer to 61", and 2) the wider the wheel spacer you run up front the worse Scrub Radius you'll encounter, amongst other issues.You can see a small list of front & rear Toyota axle widths here: http://board.marlincrawler.com/index.php?topic=11245You could try for a FJ62 Land Cruiser front axle, which measures 58.5", or run a FJ80 front axle which measures 63.5". The nice thing about the FJ60 is that you can run all your Hilux steering & brake parts on it (High Steer, Birfields, Knuckle) and get the added strength of a larger and stronger Ring & Pinion. You can run your 8" Hilux diffs in a FJ80 axle, but you'll be stuck finding your own high steer solution of go the expensive route of aftermarket knuckles (Hellfire) or a custom width front Hilux axle (such as a Diamond Axle).Again, I don't have experience with your 4Runner, but I believe you'll find the Hilux front axle to be too narrow for the newer style body.As for domestic front ends, where I am certainly no expert, you'll get mixed opinions depending on who you talk to. Personally I like to keep Toyota axles under my Toyota, or as much as possible. My limited experience with a Dana 44 or Dana 60 is that I don't like the reduced ground clearance of both, Dana 44 axles are weaker than Hilux axles, you'll have to change your wheels and then you won't be able to rotate tires with your back Toyota axle (short of unmounting/mounting tires), you cannot carry a spare third member since they do not have a removable pumpkin (unless you get a custom steerable Ford 9" or some other high dollar front end), and you can't run our EcoSeals in the Dana axles like you can Hilux/FJ60/FJ80. The upside is that they are cheap, easier to find, and have great aftermarket support. Because of this many people choose to run them. Incoming Dana 44 posts!Regards,BigMike
