need seal number for rear output shaft on transfer case....67 - L-60
or a source to obtain one........

The part number for the Transfer Case Seal (also the same for the Differential pinion) is 38189-44000.

Please refer to this thread that has very good proven alternatives:

Seals: transfer case input-output, pinion.

The alternatives don't have the same double lip construction that the originals have. They will keep dust out, and will do the job.
