Resin engine for old Tamiya A6M5c?

I have the old kit 61027:

It’s an old but nice kit (for me) It has a mix of raised and recessed panel lines, with nice details in the cockpit. I want to replace the engine with a resin item, but I’m not sure if there is a resin engine designed for this kit… The engine is a Nakajima Sakae. Any help will be appreciated. Best regards.

José.

I know of two 48th scale resin Nakajima Sakae 21 engines, however I don’t believe either is specifically intended for the older Tamiya A6M5c.
