Outer Limits 4x4 Board

Hi guys, Over here in west oz we have an annual mechanical rodeo with a mudbog event and I scored an unfinished MQ with bellhousing and a 253. Heres my drama the bellhousing is an early dellow and was not designed to take the nissan slave! They want $375 for the kit but just an old bash so cheap is the name, does anyone know what slave to use? Also it came assembled but with no clutch stuff, so Ive got the holden flywheel and pressure plate, with the nissan clutch, Number 2 drama , when the block is mated right up the clutch is disengaged, back the bolts off2-3mm and I have clutch? Im sorry its so long but Im running out of time,patience and skin!!!!
