RARE factory 4 FLU factory Automatic 63-66 radiator
 

So, for whomever is not in the know, all factory 327 equipped Chevrolet trucks with and without factory AC came with 4 FLU radiators. All 283 equipped Chevrolet Trucks with factory AC also came with them. All 351 V6 equipped GMC's had them and all 65-66 GMC's with 305E's and factory AC also had them. This is the CORRECT Harrison radiator if you are someone who cares about the correctness of your truck. If you are not a purist, then you can buy a run of the mill aftermarket one like every other Tom Dick and Harry has in their trucks. Includes top tank bracket which is annoyingly hard to find

$250 + the ride. Shipping on this heavy thing has to be determined by your zip code.
