Mazda 89 brake booster

Have changed the caliper,pads and master cylinder,but can't remove the power booster,because.........of one bolt (lower left bolt as you look under the column)right behind the steering column(can't get to it).I've tried wrenches,wratches etc,but nothing will work...no room without hitting the steering column.My question is,can I remove that bolt WITHOUT removing the steering column. Any and all help is deeply apprectiated,Thanks.
