Does it matter where the vent is on a Ford 9" rear? Mine ('62 Galaxie rear, I think) has a stock vent on the passenger side, but also has a hole (about 5/16) on the driver's side, a little closer to the pumpkin. I think it's tapped. The passenger side needs to be moved, or dramatically shortened/90* bend (spring pad now sits over top it!). Jegs has short sintered bronze vents or Currie stock-style vents (1/8), and Speedway has 7/16 vents, none of which seem to match the holes in my axle.
