Throttle & Shift handle replacements for a 93 29 Open

[29opensoon]

As the subject said. I would like to replace the Throttle & Shift handles. It looks like Go2Marine MIGHT have the replacements but they are not sure. 

Were else can I look? 

Back story is I tried to take the Tiara gold knob off and snapped it off, without much effort. undefined

Going to plan B. 

Thanks,
