You can run the Stock minitruck axles with the center section. You just have to get the front CV type driveshaft and put it in the rear. The front Axle you have to do something about the Spring Perch width. I am interested in Sky's offset axle, but it is wider than the stock mini truck axle? so I don't know what I want there.
Another option are the FJ axles. They are heavier and wider than the Mini Truck axles, but they are offset just like the sammy axles.
Here is mine during the build up. Mini Truck Axles.
I do have some vibration (35-40mph range), but I don't use it as a daily driver either.
