I have a similar situation. My truck has been converted to 300tdi (defender spec) with a r380 from who knows what engine and transmission (unknown). Both drive shafts need replacing.
Would probably prefer stock over aftermarket (cost reasons), but I've had problems getting correct fitting parts in the past
. Punching in a VIN number from my truck to determine correct drive shafts will probably yield incorrect part numbers due to the swap.
Can anyone confirm the size of the NAS spec front and rear drive shafts (if in fact NAS driveshafts will work with 300tdi trucks) before I go ordering them from a vendor?
Measurements taken from my truck:
Front drive shaft (flange to flange): 24 7/8"
Rear drive shaft (flange to flange): 28 1/8"
Any help would be appreciated.
