A little more research on a coil conversion -
4x4 D21 chassis come in five main variants, depending on factory -
LWB Single Cab (JPN, USA)
LWB King Cab (JPN, USA)
LWB Dual Cab (JPN)
SWB Single Cab (USA)
SWB Pathfinder (JPN, USA)
As you can see Australia doesn't get any SWB utility variants and USA doesn't get a dual cab. I've excluded Europe because it's of no consequence to me.
The difference in wheelbase of the two chassis length variants is 300mm, and this difference is between the third body mount from the front and where the chassis curve begins, which means that notionally the shape of the rear of the chassis is the same, allowing for the use of Pathfinder suspension geometry with a custom length driveshaft.
Items which require modification:
Removal of leaf spring mounts x4
Removal of damper mounts x2
Removal of chassis cross members x2
Transfer of chassis cross members x3
Transfer of lower arm mounts x2
Transfer of spring saddles x2
Any chassis strengthening as requested by engineer (as the wheelbase is greater than on a pathfinder - it's essentially like doing a Pathfinder chassis extension)
Fuel system modifications to utilise Pathfinder fuel tank.
Depending on what a hunt of the wreckers shows up, it'd be nice to find a pair of commonly available small car fuel tanks that fit between the chassis rails either side of the driveshaft, in front of the axle where the standard Navara tank lives (with exhaust moved). I have to ditch my Navara tank as the five link gets in the bloody way.
Still hunting a Pathfinder to cannibalise.
