F150 Crew Cab Driveshaft

I am going to set up my crew cab to lay out on a 255/35-20. Will I have driveshaft clearence issues with the cab? If so what is the easiest way to solve it (notch the cab, skinnier driveshaft, or 2 piece drive shaft). Thanks in advance.

I HAVE AN EXTENDED CAB ON 20'S AND IT BARELY TOUCHED THE CAB. I WOULD IMAGINE YOU'RE GONNA HAVE A LITTLE MORE CLEARANCE ISSUES SINCE THE CAB IS LONGER.

im layin a crewcab on 285/35/22s and the guy is gonna need a steel shaft, hey Jason you wouldnt know if the supercrews and the ext cabs have same wheelbase would ya? or atleast what your driveshaft length is from u-joint to u-joint? i think that this dude could get a steel shaft from an ext cab but im not sure cause right now hes got this fuckin monster aluminum one but he doesnt want to tunnel his floor!

I am 99% sure they are the same wheelbase.

i have the std. cab longbed - same wheelbase as the x-cab i think and mine came with the stupid aluminum drive staft =( think like a 2litre bottle.
