So how do i go about doing this ? is it hard to install a lower tie bar and how long is it gonna take ?

This is what came with the bar so what are those 2 black triangles ?

 

No clue what the expletive the black triangles are, but you don't need them. They look like they came from a toy set. lol Just bolt on the bar. If you have ABS lines, you will have to carefully take them out of the brackets, and then route your lines on top of the setup vs. behind.

 

actually i found out what they were. they are to route the ABS lines with zipties to them. the install took me about 30min and wasnt hard at all. will post pics later.
