I am such an idiot - should have done my research before buying the 35-tooth speedo. I had a TJ back in 2000 and remember changing the speedo on NP231 and assumed the same method works for NP241. I finally decided to change the speedo today, crawled under, looking... looking, and cannot find it. I jumped on the forum and found this old thread.

"This above speedometer gear change will not work on 03-06 Rubicon models. The speedometer on these is electronically controlled"
The speedometer is off about 3 MPH so I think I will just let it be instead of paying for recalibration.
