Weekly Fun Question - Test Your 71-73 Mustang Knowledge
#1
Some have indicated the questions have been "too easy" so this week's question is going to be a little bit different - - not as easy to google.

As some of you are probably aware, the mustangs built between 71 and 73, had two different axles available - - 28 spline and 31 spline. The question this week is:

What is the difference in length of the 28 spline axles from the 31 spline axles and what was the effective period of manufacturing for any changes?

I will see how long it takes to get the correct response for this oneSmile!

if i understand correctly the difference in length was 2 inches I think. Not 100% positive. And pre 71 axles had a concave oval in the middle of the flange. And post 71 didn't.

This amounts to a hint:

There is a difference in length (of one or the other) of the 28 spline or 31 spline axles on the 71 - 73 mustang. This difference in length was reconciled after a certain date.

The question has to do with the difference in length between the two sets of axles and at what point was the "difference" reconciled.

I guess this one is a bit more difficult, huh?
