i have the yota spindles and yota axle from an 88, i dunno about using parts off of an 82. i think they used different components.the only problem i ran into using the yota spindles was the tie rods.mazda rods are smaller and wobble around in the hole.so i hacked the threaded end of the mazda rod and welded it to the pivot end of the yota rod then braced it and drilled pins into it to make sure it doesnt come apart.
and thats the end result.personally i am happy with the swap and had no problems
