Everyone I've talked with says the pan from Milodon does not work. It does not have the notch cut out for the idler arm like the stock pan. They pans everybody looks for are the 187 and 699 pans. They came on big block C bodies.
Then your talking too the "wrong" people, heres the pan that fits, its a 7 qt. just like he discibed. I had one on my 75 Duster, & just to clear things up, it also fits ALL B,C & E bodies too. NO NOTCH!!
