Bought these for my retrofit, but it didn't end up happening. I didn't want to leave the ballasts hanging or zip tie them to components in the engine bay so I bought these brackets to mount them.
They're designed for Hella ballasts, but can accomodate a number of different ballasts. The bracket can handle ballasts up to 3 wide inches x 1.5 inches thick.
