I think my new borg warner is going to make mincemeat of my box, they tend to make lots more low down torque. I am looking at the Opplinger Long Boxes (short ratio) big tooth syncro vs doing the tunnel mods for a Skyline box, I haven't re-trimmed my carpets yet so now it the time although the Peugeot 205 floor pan is already an odd shape with the Cossie tunnel in it.
