I am bidding on a 7.5 northman plow on ebay, it fits a 80's chevy but I want to put it on a 91 ford f 150.. Can it be modified?? Or are mounts available?? I can't tell if it has a single pump or a number of smaller pumps?? Thanks I read this site every day!! After reading everybodys tips I have decided to park that cold atv and put a plow on my old beater truck!!
