Will this axle pair, driver and passenger side, fit into a straight 6 rear end? I have a 4 lug axle wanting to change to a 5 lug to put on after market 17" wheels. thanks, Randy
I recently had my 4 lug axles re-drilled as a 5 lug with 4.5 pattern. Try a machine/restoration shop. Only cost me about $130. 6 cyl has a 7.5" rear so these axles will not fit.

Hi Does these axles work for the 65 Mustang Shelby 350 with 9" rear end? The driver is 26" long and the passenger is 30" long, 28 spline and small bearings. Do you have the Timken bearings, seals and gaskets? Best regards,
No, these will only fit an 8-inch rear end. We'll have all the supporting parts you need for a 9-inch axle.
