the drawback of reversing spindles and swapping side-to-side is the fact you lose your "ackerman principal" on the suspension geometry. in other words, the wheels should turn in different arcs when gong around corners with the inside wheel turning in a sharper arc. if this does not happen, sometimes severe scrubbing occurs. the tie rod ends should be in line with the lower balljoints so that if lines were to be drawn thru the centers, they would intersect in the exact center of the rear axle. just so you know.
