he cut out and reconstructed the wheel tubs in the rear... and the only flex he got was downward travel...
anything "can" be done... it's just a matter of how much you want to cut/fab/alter/modify the rest of the sysytems and body....
IMHO "fit" means there is very litle non-destructive rubbing anywhere and NO hard contact with anything like the LCAs and such.... running big bumpstops to pretty much limit most or all or your suspension uptravel defeates the entire purpose of modifying you rig unless you're a mall wheeler...
to run 35s with a full usable amount of suspension travel/flex you really need to get 7+" of lift....
here's an example of a well set up rig on 35s.... 8" lift and stil a lil contact with the rear fenders...
