    I was going to do just the plain ole 1 inch blocks... but now I think I will also move the axle forward 1 1/2 inches. Does this cause any problem with cross over steering? Does the move forward of the axle bring it too close to anything in the front of the wheel? What about the rear?

    And anyone have any links to new cross members to help avoid interferance with the steering?

    Steve said it shouldn't affect anything on the crossover steering if you keep the axle moving "within reason." I'd say 1.5" is within reason. I'm not sure about the other questions.

    I asked Watson the same question over on the ORD forum. He said it won't effect the cross-over steering by moving it only 1.5". By moving the axle forward a little you will be moving it away from the back fender well. This is where most of the guys had to trim or bash it in with a hammer, to fit the big tires in there. Since the tires move towards the back when the front suspension flexes it would be ideal to move it forward a little to lessen the chances of the tires rubbing.

    I plan on running the zero rates on both axles. Especially when using the flip in the rear. I would like the tires to have as much freedom of movement in the wheel wheels when my suspension starts to flex.
