HELP!!!! how to remove ignition barrel

[Mb3d]

Hi, hope someone can advise me on how to remove the ignition barrel from my scrap rx7, A member on here needs it but I\'m very close to the point of breaking something. \\i have removed the steering wheel , indicator stalks and I\'m thinking I need to cut slots in the securing studs that hold the clamp and the cast alloy body to the steering shaft tube, or do i need to drill out the little brass pins close to the end where the key goes......

Help!!!!!........lol

Sorted, I just cut slots in the clamp studs and then used a large flathead screwdriver, sorted!
