I'm out west and around here re-cores cost about twice as much as I can get new alum rad. from a company called Silla Enterprises (Wholesale to Shops Only). I have found that you can come across used cop car rad. pretty easily for around 50-75 bucks. The trick is, The Factory used a Rad with an extra core and larger runners in the cop car for better cooling but, I have never been able to find new replacements for them. I jobbed out the Body and we did the mech. work on a Vegas Metro car and had this problem last month. We had to use a used one.
