I was given a part number from Benelli customer service for the std. thickness recoil pad for the 20ga Nova. Ordered one from Cals Sporting Armory(not a frendly place)and its the thiner youth pad which is what I already have. They will not let me return it as it was "on sale". The #61000 pad is suppose to provide a 13 3/4"LOP. The youth 20 measures 13",Is there anyone on this forum with knowledge of Benelli part numbers or what they use to measure LOP?
