You will have to remove the beam, pull the spindles and trailing arms off and then pull out the torsion leaves. You can leave the steering box on the beam. If you remove and deliver the beam and can leave it for a couple of days, I'll do it for you for $50.
It must be clean though ie: spray it with engine degreaser and pressure wash it at a car wash before you drop it off. If it's covered in grease the cost is $100!
I live in Langley. If you are interested PM me.
