I have an opportunity to get 1 '06 oem led lamp at a good price but 1 of the brackets is broken, its the 3rd bracket the one on the bottom. Do you guys think it'll still mount ok with 2/3 brackets?

 

Wouldn't see why not. You've got two-out-of-three bolts plus the two tabs that insert into the body. You could probably jury-rig the broken one to work. Depending on how bad it is of course.

Can you get/post a photo of the broken one? Might be able to suggest a solution.

 

yes
