I just got one last week and had the same question, never got a definite answer but from the specs it appears the 61405 may have a longer table. I ended up with the 60730 as that's what they stocked in my local store, and WOZ needed to move now, to make room for the Christmas tree! It worked great, I placed a small piece of plywood on the lift to make it the same width as the WOZ.
