I own a land rover swb 88" with leaf suspension all round and sitting on 33" tyres. I am looking into upgrading all running gear to be suitable for hard 4x4 driving as well as towing, and hunting. I have been looking into the Volvo c303 portal axels and transfer case as well as coil springs for suspension upgrade. I am actually contemplating to do a full rebuild from ground up, wanting to do strong diesel conversion; maybe Nissan 4.2, suspension, brakes, gearbox, clutch, ect. Has anybody done something similar to this? Please fill me in or even give ideas please.
