Ohh.. just incase someone tells you a speedo gear will work fine.. dont listen.

i have the white 23 tooth speedo gear when i had 4.10's my speedo still read 10mph Faster than what i was going. I've since removed the solid axle and 4.10's and got a IRS w/ 3.55's. My speedo is DEAD ON with the same white 23 tooth speedo gear... speedo gears = worthless

it is about a 3 out of 10 in the difficulty level to install, and it take an experienced mechanic around 15 mins.
