Thanks Thommo, I was asking because in a tech article on modding a front end for an FE/FC it suggests that EJ/EH outriggers are the best to use, so naturally I wondered if it would be different for FBEK.
as far as i know they're all the same bar FE/FC/FB/EK/EJ have the holes for the front grey engine mounts, i do know red engine mounts for EJ/EH on a HR front don't quite suit FE/FC/FB/EK
i've used HR fronts out of FE/FC's and EJ/EH's in EK's with no mods
i believe the difference in the older out riggers is that they arn't as high where they attach to the crossmember so if you put them onto a hr front end you'd have to step it down whereas the ej/eh ones are the right height and transfer over properly.
but as far as a the original post, if its in an FC now it should go straight into the FB/EK .....
