i've been told by someone that in Russia "part kits" are sold to remove the 4x4 from the Niva and make it a 2wd vehicle.
I suppose it's about taking off the transfer case and installing one single propeller shaft joining together the gearbox and the rear axle. But I am just guessing.
I would like to have a look at such kits. Can you please tell me where to find them, if you know, or at least some keywords in Russian so that I might be able to use google with them?
