From what I could find:71-3 b body wagon, certain D100 trucks, and some C bodies. Not sure about the others.
I'd think it difficult to accurately measure that without a huuuuge caliper or equivalent, the dimensions given are pretty finite for an angled measurement. But what do I know?
True, but given the next closest C-Body axle is about 1" different, it is close enough for government work. Dave
The old school method to measure them accurately was to prop up the splined end with a block of wood against a back stop so that the axle is level and tight against the back stop. Then measure the distance from the backstop to the outer edge of the flange. Dave
I use a metal ruler across the spline end and a tapemeasure parallel to the axle shaft w tape hooked on flange face.
Okay, if the next closest is 1" different then why not measure it to .0001"? Thanks Dave, it's been a long day and I'm going to bed
All these responses, and not 1 person asked what rear axle he had. 3 flavors were available in his words "Later" axle. Do you have a 8.25 10 bolt cover 27 spline axle? Do you have a 9.25 12 bolt cover 31 spline axle? Do you have a 8.75 30 spline axle?
8 3/4 axle ....apparently the 70-73 cars with 69 wagon had the 31 21/64 th s setup. Seems consistent to several sites. IDK 8.25 in a c body...yikes?! 9.25 in a c body....hmmmm....interesting! LOL!
Actually just ONE axle, working on a 71 Charger project for my son. Trying to make his dream a reality.
