Generation IV Internal Engine - Reluctor Wheel Change

I have a 24 wheel on my 2006 LS2 6 liter that I need to change to a 58 so that I can get the MSD controller to work ( for carb applic.) I can get the wheel from SDPP for like $16.00. The bad part is getting the 24 off and the 58 on. Has anyone done this change and do you have any advice ?? Thanks

call Kurt @ wheel 2 wheel

msd has 2 different boxes,, just get the correct box
