I saw a 1600 in a junkyard with what appears to be a good condition radiator. I wanted to do the 3 core upgrade and want to know if there is any difference between the 1600 (not sure of the year) and my 71' 02. I need the wheels while the upgrade is being done which is why I'm not pulling the one in my car. The junkyard wants $75 for the 1600 radiator. Fair price ? Also, does anyone out there sell the stock radiator already upgraded to the 3 core ? I'd like to bolt the thing right back in with no modifications which is why I'm shying away from other radiator upgrade suggestions.

Thanks
