That pic is of the fitting instructions for the running boards (side steps) fitted to my Jeep. The bright metal is aluminium not chrome. I paid $569.45 (Australian dollars) for them in July 07.
If I remember correctly the export tails were $690 each when I priced them for Scott.
Please remember that Australian prices are generally 3 times US prices (except for the steering wheel bolt which at $10.50 was more that 10 times the US price).
