i recently bought a 74 blazer with a 4" lift and 33s. im want ot go back to stock height. i know that sometimes there are problems with binding and drive shafts when lifts are put in (but not always) and sometimes shims are needed to correct shaft angles. im pretty inexperienced with suspensions and because i bought it with this lift kit already in it i have nothing to compare it against, so, i was hoping maybe someone had a before and after pic of what any parts that would need shimms would look like so i could see if my truck has any taht need to be removed so as to not run into problems when bringing it back down. also, is there any way to tell if the drive shaft has been lenghthened? and lastly, will i run into clearence issues with the same 33s on at stock height? or do i jsut have to wait and see? thanks for any help!!
