my truck is a early 99 7/98 i think sits really high i just read on here that the later 99 up rear blocks are 1.5" shorter if so could you change them without new u bolts? and what would a guy have to do to get the frontt down to match. wanting a little lower it kills everyone that rides and i don't want so much fenderwell showing. if some one has the blocks i need that has installed a lift let me know interested.
