OK, need some help. Wife took the Roush to vist her grandaughter and ran over a retread that came off a truck tire. She was in the center lane with cars on each side and one behind. Couldn't avoid it. Put a hole in the heat exchanger (somehow...). Called the Roush dealer- $670 Dealer says it's a Roush specific part-not a Ford part, but it looks identical to the heat exhangers on earlier Cobras... Do I have any options here? Does it HAVE to be the Roush part? Are there any aftermarket parts that meet the same spec? THis is the tank in front of the radiator with the pump hooked to it. THanks!
