well i just mounted my ballast and saw it for myself you don't have to cut it if you put the ballast over the tow hook, but the bracket for the ballast doesn't align with all 3 holes so you can only use the 2 bottom bolts. it left mine a little wobbly so I'm still going have to use a zip tie or something. theres pics of it on the 1st post
i bought a set of jdm duals without the corners i didn't find the info out but i take it you have to have jdm corners to fit properly?
If I wanted it to mount securely cause I like knowing taht shits mounted right and is not gonna vibrate and possibly damage the balast due to vibration and possibly shorten the life of it I had to cut the to tow hook or else it would be mounted wrong.
