what is it on the truck that would make putting the spacers on, difficult?
how about hockey pucks for the rear body mounts? they are about 1" height and some don't recommend stacking them but for temporary use they should be ok and cheap to do.
i was thinking of doing that for mine but for now just need a front lift to clear 35's and went with a 2.5" top gunz customz coil spacer/level. cost about $80 with shipping and only took about 4 days to get to me although they say 1-2 weeks shipping and they are very nice to deal with. i'd highly recommend them. i got em on ebay.
