TREK OCLV Fork 1 1/8 in and 1 3/8 in

[Paddy 5000]

Dears, looking for replacement fork for my 2001 Trek OCLV 5900 road bike.
The fork needs to have following one dimensions:
steerer on the top: 1 1/8 inch
steerer on the lower part: 1 3/8 inch
Kind of tapered shaft. Was if i´m not mistaking
only used by Trek & Klein in the early 2000´s.

Thanks!
