A/C Panel HELP

Hi. I'm going to buy a new a/c panel. I found this one (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=7985722107&sspagename=ADME%3AL%3ARTQ%3AUS%3A1) on ebay. However, I don't know if it will work with my van. It says to check some numbers, but on my panel I can't find anything similar. I have a blue connector, no rear, single temp. Where should I look to see if it will work?? thanks in advance
