No they will not. I believe you need the later style solid axle spindles, and then you can get hub spacers from sky offroad to use your ifs hubs and fj 60 vented rotors with your v6 calipers. Might be cheaper to just get wheel spacers if thats the case, and run your v6 calipers. Somebody feel free to chime in on this if im incorrect.
I've gone about widening and increasing braking power 2 different ways, both with really good results.
One way, FJ60 Vented rotors re-drilled to match the mini truck pattern. IFS calipers tapped to 1/2" x 20 fine pitch thread, knuckles drilled to 1/2", calipers now mount on the outside of the knuckle, very little grinding of the rotor to clear the caliper, but only on 1 side. Also, I had to use a set of those 1/4" slip on wheel spacers for the caliper to clear the wheel, which is pretty common with this swap.
Another way is to use early Land Cruiser vented rotors from an FJ40 which are vented, but measure the same as mini truck solid axle rotors, except for the vented part being thicker, so then you can just bolt stock IFS calipers to the knuckle and throw on a wheel spacer. I actually prefer this setup better. Has more of a stock feel, and drilling the FJ60 rotors out is not too fun.
