My Gran Turisimo has a sleeved nut that threads onto the upper pivot bolt from behind the dropout (rather like the way many Simplex derailleurs mounted). I just mounted it on a Campy 1010B dropout without much difficulty. The hardest part was preloading the upper pivot spring whilst tightening the sleeved nut on the other side.
