A discosportforum member is fitting side steps and hoping someone here may be able to help

Hi, anyone know what size of Rivnut tool I need to attach the side steps please? I downloaded the instructions from ToPix, but they don't show the size - typical. My other option is to wait for the steps to arrive and take it from there.

I'm hoping they are similar to RRS  Wanted a Series 2 LR since childhood but previously owned MY16 Disco Sport HSE TD4 Auto, MY13 RR Sport Black Edition TDV6 Auto, MY10 RR Sport HSE TDV6 Auto, 2007 Freelander 1 Freestyle TD4 Soft Top, 2009 Freelander 2 GS TD4 Auto, 2007 Freelander 2 GS TD4, 2004 Disco 2 Metropolis Auto, 2002 Disco 2 GS, 2000 Freelander 1 SE TD4 SW

Still hoping for a S2 one day!
