Hi guys, recently picked up a '91 325ic and am working to get her back into great shape. The car is pretty sound but came with some issues, most of which involve replacing things versus serious repair (knock..knock). I'm more familiar with my E34 and former E36s..the E30 I am learning on.

One of my projects is replacing the power retractable antenna. Thought it was just the mast itself but not sure I don't need to replace the entire unit. Anyone done this before? I see the replacement units available for sale but haven't yet pulled the trigger yet. Any tricks to this one?

Thanks for any assistance on this one!

Steve
