I'll have a measure up of mine later if I get chance. I've got 4 alloys and a spare steel and as you know its sat on7 x 15 weller with MTs on.
IIRC everything after about 96 got 7", even in steels, there are definitely 2 widths of steels floating around. Remember a lot of these website are copies of each other and where did the original info come from.
