I'm about to mount 4 Hella 4000 lights to the the roll cage, above the window on the existing mounts. I got the bolts, M7 - 1.00 x 25, but I'm concerned they may be too small. The bolts that came with the H4 lights are much bigger. Interested to know if those with Hella 4000s have drilled out the hole/nut to accommidate the Hella bolt or have went with the M7.
