I bought them on amazon, around 20 bucks, just make sure you test fit the nut onto the bolt before you get started, the nut goes into a sealed metal box, i bent the s*** out of the next closest hole on one side to get the nut tight after the tool broke off.
If you are referring to the cargo tie down points they are plastic and do not support any weight whatsoever. I replaced mine with some i picked up at walmart for about 12 bucks. I hope this helps.
Hood Lift Shocks
Installed hood lift shocks today, the passenger's side went on with absolutely no issue, but, the driver's side was a real pain in the dick.
Changing the head unit to a 2 DIN stereo is totally doable. not sure if I'd want to, seeing as you would have to cut apart the dash to have it fit, but, the 2 DIN spot is still there.
