I’ve used the axle stands on the rear by using the supporting torsion axle ( the big U that supports the rear wheels) and it allows for a nice safe environment. Up front , I’ve used the jack and the stands in the recommended locations . I wasn’t real sure of the safety though . So I kept two floor jacks under the body just near the lower A arm mounts . I haven’t crawled under the front at all , I don’t feel comfortable there , but the rear is super stable . My preferred method is backing the car onto long ramps with the clearance to go underneath without fear of collapse.
