I've heard that.
I'm more wondering if there are differences between the big bolts. im figuring if the big fenders are the same and they look good on a 4100 with a 34.5" diameter tire then they would probably look good on my 3800 with 33" tires.

i think they would look out of place on a 1/2 ton but my 1 ton with bigger tires has more in common with a 4100 1-1/2 ton than a 1/2 ton with short tires.
