E30 Zone

Hello everyone, I have a e34 525 as a donor car which is complete at the moment, does anyone know what gearbox came in theses (manual) and can I fit it with the motor into my e30 or do I need to source a ZF (e36) gearbox with the e36 flywheel and clutch ?
Thanks in advance for any help guys
