Kind of a hard question. First off, any bell housing that will fit the 283 will not match the bolt pattern on the 42 trans, so this means no 42 trans. Next, any bell housing that fits the 283 will not have the brake/clutch pedal mounts for the 42. What you could do is, get a 283 bell housing. Pre-fab the clutch/brake pedal mount and attach it to the bell housing. Next find a 49-54 4 speed. It will have the correct trans pattern and will link up to the torque tube drive. A better swap may be update to a later open driveline set-up. Just a couple possibilities. I'm sure there are more.
