Yeah, just springs at the back.
Tbh the backs will come out with a crow bar in a matter of a seconds, just a simple jack up and jimmy them out.
The fronts take a little longer but a providing you have spring compressors/don't mind playing a bit of Russian Roulette you will be fine.
For the backs budget 15 minutes but for the fronts 90 minutes.
It will be harded to reverse the process however.
