I've got a B&T 833 mated to a slant that I know for a fact that the trans is in good running condition (I was driving the car before I parted it out). I've also got an A/F Body 833OD with a slant bellhousing still attached that I bought used. The seller ( a friend of mine) had no idea of the condition of the trans. I will be leaving my 65 Dart wagon slant-equipped (with extra goodies of course) and converting to a 4 speed. Which 4 speed to use - the 65 B&T 833 or the OD 833? If it matters I will be using an 8.75 with 3.23 gears.
