Old coil CDI combo

I have an very old gator with a K engine KF82D-X. The coil is a CDI coil combo and has failed. It is no longer available. I am asking for possible solutions to get ignition working. Using newer separate CDI and coil, reconditioning original, or finding working replacement. Any help will be appreciated.
Coil info is KOKUSAN DENKI.CO. 1U21 827H 340
Thanks
