No, it is like the following picture. I did find a rebuilder in Selma, OR and have sent him my old one for rebuilding. Pricey, but has a 3 year warranty.
392 . . . . 1957-1958 . . . . . . 1671893
The 392 pump is on the right, a Dodge 315-325 pump is on the left.
Although they look similar they do not interchange.
Note the slight difference in bolt positions, the 'top' mark and
the contour at the bottom.
