Yep, in my original line drawings of a KT with Porsche turret they extended forward completely covering the lower debris screens but with the kit I got when I bent it into shape and put the back end where it should be they only went up that far. So I thought that's strange... but I did find some reference for the shorter screens someplace so I didn't worry about it too much...
