Speedi-sleeve for MFI cam drive

Looks like my oil leak at the cam seal for the MFI drive pulley is back. After a closer inspection, I think there is a nick in the seal surface on the cam shaft. I see that our host offers a Stoddard Speedi-sleeve for this, but I suspect Stoddard just re-boxes a NAPA, National or Timken. I'd rather pick one up locally instead of waiting for one to be shipped. When I put my ancient German-made non-digital micrometer on the end of the shaft, it reads 1.375", which is 34.925 mm. The 99139 part number in the brands above are to fit 1.375-1.381" (34.930-35.080 mm), the 99138 1.371-1.377" (34.820-34.980 mm).

Which is correct? If I trust my mike, I'd get the smaller 99138. But if the shaft is really 35.000 mm (as seems more German), I need the 99139.

IIRC there is room for another seal on top of the original one in there.

Thanks, Mark, but I've already tried the second seal to no avail. Pretty sure I'm going to need to sleeve the shaft.

No input on which I need? Those 2 part numbers don't have much overlap in fitment.

Calibrated digital calipers (2 different ones) measure shaft between 35.008 and 35.013 mm. So I will pick up a 99139 sleeve tomorrow morning.
