H HHStang Member May 15, 2003 566 0 16 Coastal SC Jun 16, 2005 #2 Jun 16, 2005 #2 My guess would be no. The 71's were like 60" hub to hub, the 69's were maybe 57"?

The rears from 67-73 will fit. 28 spline in all, unless it's a Drag-Pak rear. Another way to get 31 spline is to find a Lincoln or wagon pumpkin, and change the gears, and find the 31-spline axles.
