I have done it twice. And it is a PITA. Six bolts, that are not easy to reach, and they are usually too rusted to remove the normal way. In both cases, I wound up using an air chisel to cut the old bolts off and replaced them with new stainless ones. Also, while the first one I replaced was the same cable type as the one I removed, the second time the replacement from Toyota was a chain type. Apparently Toyota has stopped selling the cable style, and is now selling the chain type instead.
