I'm attempting to take a set of rear disc brakes from a 2003 Dodge Dakota (12.25" rotors!) and put them on the rear axle from a 1998 Dodge Dakota

I say attempt because I've run into a problem.

the axles are not the same! they welded the flange onto the axle tube in different spots

(see pictures to illustrate--click on link in thread title for full size pics)

This picture is the 2003 axle, the flange is 5 cm from the end of the tube
