Look under the front cross - the side plates come down slightly below the actual cross (by about 1/4 inch) - pretty sure thats the trim spot - when you look at the instructions page 2 photo 8 the down brace with the 3 holes... slightly longer on 10+ models... I would think that unless its a foot narrower the Blue Ox would hit that corner as well.
Just trying to be helpful no need to get snarky.
Snarky is MY territory lol.
EDIT: as a matter of kindness - here is the blue ox instructions
- they have ya whacking off a good six inches (photos 6-10) of the pre 10. - the blue ox (like roadmaster) attaches to the frame rails while the currie attaches to the bumper and cross. I prefer the blueox or roadmaster design for strength... but the currie gives ya a real nice front skid!
