I used this for a 73 x 124.5 mm stock BB.  As I cannot seem to find that size (124.5) anywhere, and it works great!  Just note you install the right side first as the left side is plastic threads (hence the lower price than a UN55, they were also black not white as pictured) and you install that second. Since I brought the bike back from the dead and am selling it, this part got the job done! If i were to keep the bike I would spend the extra $10 and get the UN55. I would have added photos but the part is already on the bike and hidden by the frame and crank set.

Gets the job done! Will replace 124.5 BB!
