1965 Nissan Patrol KL60 Rear Axle

Hey all,
I have a '65 Nissan Patrol KL60 with a busted rear axle. I've been looking everywhere for a replacement, but to no avail. I know I have the option to have one manufactured, but that is damn expensive! I've heard tell that '77 and earlier Toyota FJ-40 Landcruiser axles are interchangeable with older Patrol axles, but I am not sure if this is true, or how to do the conversion. I had a friend who owns a wrecking yard find me an old FJ-40 axle, but I need some help with the installation/conversion.
Any help would be greatly appreciated! :biggrin:
