Kitchen Aid Mixer: How do I replace Levers?

I have ordered and received new levers for this mixer from Applinance Parts Pros.

The parts are #WPL 9709276, Lever-Speed, and #WPL-9709280, Lever-Latch.

I have dismantled the mixer, however, each lever is attached to a rod that has been crimped onto the arms of the levers.

How do I remove the ‘old’ levers without damaging the (crimped) rods?

How do I assure the rods won’t fall off of the newly attached levers when I re-assemble the mixer, or when the mixer is under use?

Thanks,
