The black coating is wearing off from stepping on them and winter road grime, otherwise these are in excellent shape. No cracks, gouges, chips or chunks missing from the metal. The previous owner had the bolts seize up in the step, so they have been drilled out and replaced with bolts (with hand knobs) and nylon lock nuts, IMO a better system anyway.
$300 plus shipping from 58103, I would guess about $60 +/-. Or $100 per step, plus shipping.
