Will it fit a KJ front bar?

no it wont but there was a thread not to long ago about someone on here trying to mod it to fit. the verada one is too wide i think and a bit of an awkward shape

That's unfortunate. Cheers. I did do a search, but of course you can't search for TJ and KJ.

How bout this?

If that lower set of vertical slats were black that'd look even better!
