The majority of Italian mobsters aren't tall guys. Castellano was often described as 6'2" or 6'3", but if you look at his booking photo from his 1985 arrest, the one where he's standing next to the height chart, he's nowhere near that.
He was 70 and people shrink when they get older as their spine curves and the disks between their vertabrae gets thinner. He could have easily lost 2-3 inches
