That's fine. Knowing that the sumosprings can be trimmed easily enough, I went ahead and did the same with mine, using a hacksaw.

I haven't set it back on the ground yet. Had to take the wheels off in order to turn the wrench to tighten the u-bolts, and I'm just leaving the wheels off until I get the tires changed. That'll give me a chance to go through the rest of the suspension (esp the shackles), the brakes, and the hub bearings.
