i would use new springs with new new shocks.
the cheapest would be very low miles used springs from fj cruiser.
otherwise buy some moog 81108 front coil springs, for the rears i recommend you skip the moog 81081 and use some bilstiens b12 36281824. the fitment is was better, but back then 5 years ago when i bought the moog coils, i paid less than 150 for all 4.
