The aftermarket “OE style” ones fitted into the mudflap slots Ok when I swapped, on both my TD6 and TDV8. I just added a screw underneath to hold them together….. when the garage did them on my current car, looks like they used the same fittings.

Y'know my side steps got so dodgy I had to have them removed before they fell off following a very serious mot advisory on them.

My fatty now looks much more modern without them in my opinion ( and my wife's opinion ) and since I have discovered how you can lower the suspension to access mode before you actually stop on the drive there is no problem climbing in and out without the steps. RR owner
