Ted, you're very welcome (<font size="-2">that's why I'm the Keeper of the Photos</font>)
Yes, very simple really just cut and widen. The belt setup does not change it is the same for both the QAxx and QAxxA. The only change came with the QAxxB which was for the 82 series Cubs which used a 5/8" belt rather than the 3/8" belt that the narrow frame and non-82 series wide frames use so, on the QAxxB the pulley is wider. Hope that made sense.
