it should measure the tail stock and check if 700r has a cable style speedo hook up
I don't think a 700 has a modulator valve depending on what year 700 you have you may have to run a tv cable up to the carb to controll your shift speeds not sure but just somethign to think about
go to www.montecarloss.com theres conversion charts for transmission lengths.
