From the picture, I can see that the radius-rod mount is 'way-back'. So, I agree with the above post, 'late', meaning 42-48 for sure, and probably 41 also, as I see in the green parts book that 41-48 (replacement) is supposed to be the same, part no 6A-4504. The parts book also says that 41-48 also takes the same driveshaft, indicating that the lengths of these parts for 41 match 42-48. In my view, not worth much. The radius rods that go with them are probably worth as much, or more (for 32-34 conversions). If it were me, trying to use this tube for a Model A-thru-34, I'd be looking at getting the center bearing out, then see if a 'early' driveshaft (either L32-34, or Spadaro 'kit') would fit through there, then go from there.
