"Big bolt pattern conversion axles" fit any '65 and newer, 5 x 4 1/2" Mopar spec rear disc or rear drum brake package.  

  • 8 3/4" rears came standard with 30 spline axles.  Running 35 spline axles in an 8 3/4" rearend requires a spool (not Mark Williams).
  • A popular upgrade for cars with 8 3/4" rears is to swap the original rearend for a cut down Dana 60 truck housing with 30 spline axles.
  • Mopar passenger cars equipped with Dana 60 rearends came with 35 spline axles.

Please make sure you know what you have before buying replacement parts!  Stock length axles are available here.
