Cheers for the pic!

These are the ones correct (pic taken from the net)? The EF2 never had those, only these ones which are held on with a few welds onto the bumper support.



This is the EF2 bumper support




And this is the Concerto one, you see how the mount to the chassis is alot further back compared to the EF2.



here it is with the bolt mounting face lined up with the Concerto one, you can see how the top part is not even close to the bumper support
