Replacement flywheel Parmakit

Hi,
Some time ago I bought and installed a Parmakit 1600g ignition kit for my Quartrini cased small frame.

I bought Item number 75043020 

Last week while I had the flywheel off I dropped it and smashed two of the magnets on the flywheel.

I couldn't find a replacement listed for the small frame 19mm model , only the PK/PX 20mm 

Really hoping there is something available as I don't want to have to buy a whole new kit. If anyone can help out I would appreciate the information.

Cheers

Richard
