I have the round pattern 205 in my truck .i just lost the clutch disc and have everything out right now. it sure would be nice to slip in an overdrive right now. the checking i have done i dont think i would have to change drive lines.the nv 4500 set up would be only .125" longer than the present setup.my 465 leaks pretty good . so i am trying to decide to over haul it or pony up for a new tranny.anybody know of a killer deal on a nv right now? thanks
