i asked that same question a while back, here's what i was told from Rene "Your current 241 has a 27 spline input. You'll need a 81 or newer 465/208 combo which will have the 32 spline output and correct adaptor, and you'll need a 32 spline input gear for your 241 (they're dead easy to change).
Install new input gear, remove 208 from 465, install 241."
