search google for a good website...
do not buy from ebay...you may not get all the parts you need.
i picked up an AC Gauge from eBay a month ago...have ordered many things with NO problems. use common sense and read the item info CAREFULLY. if you aren't seeing all the info you think you should contact the seller or better yet, don't buy that item. it just bugs me when people discredit eBay...obviously it would not be operating if it was SUCH a bad place to purchase items. good luck finding your gauge
