1970 Dart Steering Column Disassembly - Help Needed

Thanks for the tips guys. I ended up using a puller with a washer as Backally suggested and it came right off. I removed the housing the holds the ignition switch to clean it and am having some challenges getting it to reseat. Any tips to getting this thing back together? The shifter seems to be lined up properly with the plate on the back of the housing. Any help would be appreciated!
