Yeah i was gonna cover the adaptor soon. My adaptor was cheap ($300 cad) but it isnt really available anymore. Im using a North West Fabworks Adaptor. It adapts the tranny to the auto bell housing and uses a T-56 internal slave cylinder. They only made a few and they arent making them anymore. Other companys make the same adaptor plate though, albeit much more expensive. I had a lot of problems with the adaptor plate but i think its sorted now after swapping plates a few times with NWF.
Im using a machined 3VZ flywheel and marlin clutch. In hindsight i wish i would have done my own research to see if a 5VZ clutch and flywheel would work because i feel like it could work but i couldnt find any decent info online
