f350 blocks, 350 ublots too short!

[TheDurtyDeez]

Hey guys I am trying to stick some f350 blocks in the back of my f250 cuz the level kit brought the front up too much! I got her all torn apart, the 4" block in and the ubolts (new from dealership) are too short... I also come to find out they are the exact length of my f250 bolts!!

Could someone tell me if this is right and I just need to start a thread and crank em down... or perhaps tell me what an f350 ubolt length really is!?!?!

Its all jacked up and torn apart so any help would be GREAT!!!

THANKS in advance!!
