The p/n that you referenced, p/n 497K02771, is a kit that can only be ordered through your sales rep. This part will come to you with instructions and the Post Script module. Not sure if it has the latest software on it though??? If that is not an option for you, then you might be able to try asking your Xerox Technician to order it for you, but the part number is going to be different for your tech. Your tech. should order p/n 540K02667 and when it arrives, he can then install it and upgrade it to the latest software level. There should be plenty of these parts available from Xerox in the U.S.
