Sorry if this is a Hi-Jack, but I posted a sort of similar question before with not much response...
Zig, what did you used to cut your fenders, that looks really good.  Do you think a 3" BL and trimming fenders like yours would help clear 31's ?
I used a cut-off wheel and a sawsall (sawsall for the majority and the wheel to clean it up) then I used the same weapons to cut out the relpacement sheet metal and then cleaned it up with a bench grinder (after bending it to shape)
