PLEASE HELP! Bagged front questions

[randomhero472]

I know, i know.. i've searched for hours tonight but havent found the answer to my question, so here goes... I'm bagging the front of the truck, standard re7's w/SD brackets, i'll be running a 255/35/20 tire ( i think 27" overall) w/2.5" ece drop spindles

I would like to know if my stock fenderwells will be too shallow for the truck to be fully aired out, and to throw a kink in this i'd like to know if i need to bother w/cutting my lower cups down to 1.5" ....if the stock fenderwells will be in the way, i really have no problem using aftermarket/trailer fenders for fenderwells, but would like to retain the stock wells if at all possible, and dont want to cut the cups down if it wont make any difference in the long run w/the tire already hitting the fender well

Any pics of bagged suspension on bigger wheels or 27" tire appreciated, as is any info... thanks, hope i made this as confusing as possible
