Older Mirage Drive broken/upgrade

Good day, I recently bought an older Hobie mirage Revolution 13. Its been great on the water. Recently did a V1-V2 Upgrade. Once I did the upgrade within half hour on the water the connection between my fin mast and the sprocket shaft broke. In doing some research I found that it appears that I may have a drive system that is older than even a V1. As i look at parts online the appear different when looking at my drive system (see images). Im seeking advice as to what parts I would need to replace this broken drive and bring it up to speed. Currently I believe I need a V1 Mirage Drive Sproket shaft, 2 V1 or V2 (not sure?) injection molded sprockets and two ST fin masts. Please confirm or let me know of how I might be able to fix this issue and get back out on the water! Thanks.
