I have this exact conversion coming up, in the not too distant future. I curious to know, how can I tell for sure that this is THE correct pan. Don't get me wrong, I certainly not saying that you are incorrect, or that I doubt any part of your description. I'm just asking if anyone knows of reliable source of this type of information online or elsewhere where you can find descriptions with hallmarks (preferably pix too) that would show the application of this and other vintage Mopar pans and their applications. 440 Source seems to have 1965 0r 1966 on covered with the numbered pans, and they have info showing that this pan would be a #2465195 or a 2402307. This is purely based on your description. So can anyone say what it is for sure?? Again, not doubting any info, but there are no numbers on a old pan, are there? I personally would not know the difference if you said it was a #2268459, 2463448, 1944694, 1737768, 2206455, or a 2532401. Looking forward to an education on the subject. BTW, this kind of info on valve covers would be golden as well. Thx, Lefty
