This is one of the better video's on replacing the Roadmaster steering stabilizer.

I like the Roadmaster mounting bracket much better then the Safe-T-Plus mounting bracket !
As for drilling holes ? Not sure where that came from on the Safe-T-Plus install ?
The STP mounting bracket , you have to remove the drivers side ASB mounting bracket , install the STP mounting bracket under it then retighten.
THAT'S where the problems come in.
If you notice in the video on the Roadmaster stabilizer install you can see the boxed frame and how thin it is , how many threads can be tapped in that ? 4-5 ... and that's the bad quality on ford's part with no added welded nut or ? inside the frame .
