[69L89396]

Thanks Stefano,
Not to dought your memory, but does anyone here on this site have a '69 Camaro 396/375 manual that has the original radiator that can confirm this? I have called several sources and nobody seems to know what exactly this is supose to be. Everyone I talked to said the only way to know for sure is to find an original car and get the information off it. I have called Jerry MacNeish but have not heard back from him yet. He might be able to confirm this.
