I have the same from Dark Horse for a TKO and it does fit, but it does not have a good drive line angle. I spoke with him when I got it installed and he said yes that is how it will fit unless you mod the tunnel, or I guess someone mods the case on the gearbox. I moved it up as much as I could, but still bad drive line angles IMO. I have the older TKO (4 years old), not sure if the newer models are dimensionally different. The TKO is getting the ax back to a 4 speed as that is all I need and can use a better racing gear box. The TKO just does not bang gears as good as a top loader or T10 type of box without a bunch of work (again IMO).
