Hi there, i have the JDM/TRD cover/cap, i actually tried toput it on and i couldnt do it, so my friend did it, it looked very simple, what he did was drill out the OEM hinges... then attacted the unit... instead of using the screws that were given we used bolts so it would lock in and be more secure... if you wanna see some pictues click on my link below, any questions PM me
