Would anyone know the rear axle length of a 7.5" 66 mustang? Also, I think they were all 28 spline, but if that is incorrect, let me know. The reason I ask is, I found some 5 lug axles online for the 7.5" rear, and I had never seen them before. They come in all different lengths though, so I'm not sure which to get. Will this even work? Hopefully

 

i believe the early rangers used a 7.5 which was a 5 lug link us to them or ask the seller if they will fit your mustang

 

The length is 57.25 inches from flange to flange.
