Excellent find. With the 4 speed and the A- code 3.50:1 Trac-loc rear axle, you should have 31 spline axles, the 1330 u-joints and possibly an N-case rear end. It's about the best of the best in '73.

Looking forward to seeing your progress.

Thanks! When I looked up the "A" axle code I thought it said 3.50:1 open rear. Am I missing something? I'd love for it to be the Trac-loc...

Ooops. my bad. The A is an open, but the 31 spline goodies should still apply.

I might be wrong but I think only R codes and boss got the 31 spline. Of course the BB cars also. The end of the axle will tell you without pulling. Google the difference I forget, lol.


When a man is in the woods and talks and no women are there is he still wrong??

To each their own! If it's all original it probably has some surface rust but in my opinion I absolutely HATE looking at rust!

71-73 Mustangs never die, they just go faster!

The 71-73 351 cars with 3.50 or numerically higher rear gear all received the 31 spline 9" and the larger 1330 U-joints and matching driveshaft.

Typically the 31 spline axles will have a large center countersink, with two smaller ones on either side. The 28 splines have a recessed "double D" shape int he axle end.
