Mine is a stock replacement for a mid 80s 360 in a Wagoneer. But, they are all almost the same. The major differences are if they have AC or not. The pumps for those with AC are built up next to the left bolt so you don't need a spacer for the brackets. Other than that, the mounting surfaces are all the same. Are you sure your not ordering one for a Dodge 360?
