'66 Barracuda rear axle question

Thanks Roger! I think I'll be able to figure it out from what you said. Yeah, I have been meaning to order a FSM on disk from E-bay but just havent yet. The previous owner has a real-deal '66 FSM that I'm going to grab next time we see each other.

So do you really think I need to take the axle in to have the bearing pressed off and new one on? Could I get away with a nice ol' cold chisel and my 5lb hand sledge? then use a big socket to drive the new one on?
Being a full-time student makes you cheap :)
Any tips on which brand bearings to go with? Tmiken or whoever was what I was thinking
