Hey Fris, when I mounted the plate I used the original bracket that I took off the fender. I then fabricated a upside down "L" bracket. I drilled and mounted that to the bottom of the trunk then to plate bracket.
I posted tis because it took about 10 minutes to figure out and about 30 to fabricate.
p.s. From another thread......I have an 02 with a Nikko G-pack(TRE, timing retard eliminator) and my restriction is gone. Also I got way more throttle response 1st, 2nd & 3rd.
It took 5 minutes to install. Opened the tank foung the connector plug and play.
