73 ply roadrunner leaning on one side.

hey guys i seem to be having an issue with balancing out my 73 roadrunner..it seems to be leaning on the driver side. i just had the rear leaf springs rearchd to clear some 15x10 rims with 295/50/15's. both rear shocks are coil over and are brand new. is it possible that the left rear shock is defected and causing it to lean?
