NP241 is very similar to NP208, except it is set up for electric speedo. They were found in 90-91 V series trucks. That would be a direct swap, if you can get the 4WD 4L60E. Worst case, get the 4WD output shaft from the 700R4 in the Blazer now put in your 2WD 4L60. That would be a good time to freshen the trans so you know what you have.
