Is the LWB Gen 1 box different from the SWB? (Different bolt pattern like the gen 2 box, lock to lock turn count, bigger internal piston for less effort, etc.) Any advantage to it?

I read on the Gen1-Gen2 swap sticky thread that the idler arm is stronger on the Gen 2 vs the Gen 1, but the arm itself is slightly longer. If I use the Gen 2 box with the Gen 2 pitman arm and idler arm, other than a slight toe change and a slight decrease in lock to lock turns, (If the arms are indeed longer) any disadvantages, advantages, or clearance issues?

Thanks for the answers so far! <img src="/forums/images/graemlins/cheers.gif" alt="" />
