hey would anybody know if an eb bull bar would fit an ef and what do i need to mount a bull bar or does it just bolt straight onto the mounts the bumper does i kinda hit a roo and thinkn better put a bull bar on me car cheers

Should fit but may need modifying. We put a 5-poster from an XH (EF) onto an XG and only needed to make up new mounts.
Most will mount to the same point as the reinforcement bar for ya bumper mounts to.
