Available options include machining of the yoke to accept Chevy/GM U-joint (add 91048339) and lightening of the ring gear to remove weight (add 91600013; 5.37:1, 6.66:1, 6.83:1, 7.00:1 ratios are already lightened).
These axles have 4" of spline which will allow you to cut a maximum of 3" of the spline off to obtain the correct length. This is perfect for small shops and will allow you to build your own custom width rear end easily. Axle length is measured from the flange to the end of the splines.
If your class does not allow a grand national rear end this is your best choice. These housings have new centerless ground 3" tubes installed in reclaimed original Ford 9" housings and have the end and metric brackets jig welded in place. We offer this housing with either centered or 2" offset to the right pinion locations. Works great with Currie cut-to-fit axles. Axles sold separately. IMCA Approved.
