its made by vis
and i did a research... most people have vis ones but they dont have the key hole pre drilled.. i would of left mine without it...
its weird.... i searched it for soo long and have not heard of a problem like mine

 

here are the pictures of the trunk... u can see how there is no bracket

 

That Kinda sucks!
Perhaps fashion an aluminum spacer that can be tapped for the bolts and epoxied in place ?

 

imi thinking about fusing/cementing bolts on and bolt it on... not sure yet..... i would of just left it without a hole but it was predrilled

or i can make a bracket... but i dont know what i would use that would be easy to play with... like drill holes and what not

or i could put a plug... but not sure about that
hmmmmm... what to do.. what to do

 

now installed
fitment is really good... in order for the best fitment i took out the trunk springs

 

Looking good!
