Can someone who's done the big box conversion quickly list the parts I'll need for it and what trucks to get them from , as I fear my gearbox doesn't have long left.
Thanks

FS5R30A from a D22 Navara, turbo z31, SWB R20(spanish assembled) or nissan skyline gtr/gts4.
TX10 transfer case(chain driven)

ps you need the same ratios and bellhousing pattern, so the best bet is from a TD27 powered R50 Terrano, extremely rare.
Others have used the Navara QD32 box but had added complications with dual mass flywheel

QD32 Gearbox and Transfer, i think mine was from an 06 D22 navara
Td27 clutch,
Longer Clutch pin (i made mine out of a broken screw driver)
I used a different crossmember but had to drill the gearbox mounting holes anyway. Dont remember what car it came from, told wreckers i wanted the one that came with the gearbox though.
Im still using original driveshafts, got a 20mm spacer for the front drive shaft and have left the rear the same. Havent been off road yet so dont know if i will have any dramas with the rear diveshaft
i think thats about it.
