UPDATE :

The CompTech Short Shifter requires the use of LocTite glue to stick the shifter to the OEM knob..

What I did was to use the supplied screws to hold it in place without using LocTite and after one month which includes hard shifting to see how it holds... I dismantled the console and had a check... the screws are still in place...

Just a note to those who are planning to install one of these that's all..
