another gear change and speedo gear ?

Ok now with the 4.10's and the 140mph guage, I am reading 140mph when I am really going about 75. I would like to know what speedo gear I need to un@#%* this.
I have a AOD with 27" tall tires and the 4.10. Anyone know? Thanks

well not sure with the larger tires, but I recall 4.10 being a gray 23 toothed speedo gear. someone correct me if I am wrong.
