IH OAK Posted October 31, 2021 Share Posted October 31, 2021 I saw on here in an old post where someone mentioned that there was a company that made conversion kits to put a 4-71 Detroit in a WD-9. Does anyone have information on these kits? Who made them? Were the rear ends able to handle that much power? Quote Link to comment Share on other sites More sharing options...
