Edit feb 2024:
The info below is not entirely correct. See post #25 in this thread to see why the E10/24 part 32 31 1107 627 likely does fit.

Measuring them side by side, it seems the part 32 31 1107 627 is not a direct match. Reason are 2 aspects:
1) the inner dimension of the ..627 bearing is 0,2 mm too large. Its 18.2 where the spindle seems(*) to be 18.0
2.) The outer dimension of the ...627 is 32,3 mm, where the hole seems(*) to be 31.6/7/8. You won't get it in.
*= It could be that the actual diameter of the steering spindle and hole opening is different to what I post above: I can only measure my assembly just next to the bearing/ hole, as I dont want to split my zero-play column.
The ...627 is 21.9 mm long ( original is 16mm) but that extra length would not be a problem; it will actually fit (at least in my steering column; may'73 3 ml 0 cs).
The ID of the ...627 bearing measures 18.2 mm. So the axle would be 0.2 mm loose in the bearing.
The OD of the ..627 is 32,3 mm, the hole seems to be 31,6/7/8 mm. It would be too large by 1,5 ~ 1,7mm.
Possible options:
1. The ...627 part could be used, if you insert a 0.1 mm sheet of copper for instance. It will compensate for the diameter difference quite exactly.
Also you need to overbore the hole to 32.3. Pretty difficult.
2. Any bearing with 18.00mm ID and OD 31.6/7/8 mm, with a width between 6 to 22 mm will fit.
Can anyone with a disassembled set confirm the measurement from the actual bearing to spindle contact surfaces?
