I have a Mitsubishi 2003 Lancer. Recently the radiator broke, i tried to get it fixed but it broken in the wrong place. I then went to a mechanic to see how much a new radiator from the manufacturer would cost, and it would be around $200, being strapped for cash i looked else where and was suggested by a friend to use rockauto.com i looked and found 2 radiators for my cars one cost $110 and the other $150. i looked at the details and some of the numbers seemed different. http://www.rockauto.com/catalog/x,ca...,parttype,2172
the $110 http://www.rockauto.com/catalog/moreinfo.php?pk=499677
the $150 http://info.rockauto.com/VistaPro/De...talog?searcher[proliance_part]=432484&search_proliance_parts=SEARCH
I was wondering if there was a difference or if anyone had a suggestion as to which one would be better to purchase or if anyone know of anywhere else to buy a radiator cheaper that would also help.

I do not know much about cars. This is my first car i got and it was used previously. If anyone knows anything that might that would be great.
Thanks
