raising using blocks??

[J_Dub]

anybody use blocks to raise their leaf sprung lux?
i know its not ideal but i only want to raise the rear only 20mm, just to level the truck out, the only thing i want to do is level the ass end out or maybe bring it up 10mm higher than the front, as with a bita gear in the back or back seat passenger it sags a bit, i dont realy want to alter the spring in any way, as current old springs flex quite well, and i dont wana spend a cent on spring mods untill i do it all properly and do a coon swap etc, so no dramas with 20-30mm blocks??????

i couldnt see a problem with it aslong as your ubolts are long enough and you drill the blocks out and bolt them with the springs so they sit in the locators.

dunno about the legality of it but my mates got a redneck F150 down here with 40" tahs on it, the front is coiled and lifted and the rear leaves have had a shackle flip (the shackels usually point up and now they point down) and hes got I think 6" blocks between the spring and axle. I think the bottom of his doors are around chest hight or something like that?
