personally, I would recommend the toyota complete axle swap. try to find one with drum brakes and then the master cylinder doesn't need to be swapped out unless it is still the original single system style. like said in other posts, driveshaft mod, spring mounting pads mod, some brake line swapping and a park brake connection. toyota should have the same bolt pattern if you look around for it. grab the old toyota driveshaft or at least the diff connection end of it, for the driveshaft shop to work with when they fab your new one.easier for them and cheaper for you if they have both ends they need to start with. a lot of hydraulic shops would be able to fab a conversion brake suppy hose from frame to axle, here anyway, otherwise a bit of ingenuity could fab a steel line on the frame with the old SAE brake line fitting on one end and a toyota fitting on the other end to connect to the frame to diff hose. doing that will yield a diff and brake system that is easy to find parts for in africa.
