I installed a Razo RA 90 in my car with a manual shift boot from a GXE.

You have to completly remove all of the plasic around the shifter and the knob then get a shifter console out of a manual Sentra so the shift boot covers the shaft then install the Razo it is a push down type knob so when you want to shift from P to D you have to push the entire knob down.  Then  you have to wire the OD button to a push botton switch somewhere.  Once you do all this there is no going back to the stock shifter though
