my concern would be the L series pressure plate fitting inside the A series bit of the bellhousing you are grafting to the L series part

L series boxes all have the same input shaft, same with everything else that runs 71 series boxes
dont have to use a bluey box, can use anything 71 series as all the bellhousings are interchangable. so Z series CA, SR FJ, VG...pretty such endless supply once you have the bellhousing sorted

but as DD said there is a stock clutch that does the job, think the only L series vehicle to run the really small size were 1600s or something like that, then pretty much every over 4 cylinder(apart from 720s and Z18et) ran the 200mm clutch, then 6s ran 225mm
