I was looking at my racer and a friends Southdown slider eqipped 110 yesterday, thinking about rock sliders, and I think there will be a problem. Mine is ex military with the old style flat locker covers as in
this picture (not very clear). The doors extend down below the top edge of the sill. Southdown Rock sliders and, from the pictures on the scorpion site, theirs replace the sill and extend out side the bodywork so you would need to trim the bottom edge of the bin doors. I don't thing the base of the bin is low enough to interfere with the slider.
Will probably get round to fitting sliders to the race at some point, cutting the doors will be no problem as she's been cut about a fair amount already.
