I'm upgrading and installing a t56 into my car. No kit for this. I will be cutting whatever I have to in order to get the proper driveline angle. You can do anything if you're not afraid to cut up your car.

Have you considered jamie's OD gearset for the 833? Gears 1-3 are basically the same as 727 with 4th being .80. The OD ratio isn't as good as the .64 available in the TKO's however if you're building for max torq and didn't need to run a super high rear gear it could still be a good combo. And you know everything will fit right because the guts go inside a regular 833.
