Ahhh bastad thieves

me so cross. Went down to euro car parts after work, bought new ignition lock barrel, ignition switch, steering lock and new sheer bolts. I thought i would sort igition out and worry about matching keys later. So gets home at 6 oclock ish, took steering wheel off and strip down steering column. Sound took ten minutes. Just spent three hours trying to get knackered steering lock of inner shaft, It wont wont and will not come off.
Any ideas any body. please.
Gonna leave it now untill tomorrow pm as lost my calmer now.
