Axle widths?

[Radar]

I used a complete front axle kit ffrom Posies rod shop. They have alot of combinations of axles,springs suspension parts plus tech guys for help. My axle is 46" kingpin to kingpin with a 4" drop. The spindles are 47 ford car with 67 mustang GT kelesy hayes disc brakes. All ford spindles will fit from 28 to 47 on a car and maybe 1/2 ton pickup axles. There are alot of aftermarket parts availible for these front ends. I've gotten alot of front end parts from SpeedwayMotors as well. Radar

I used a 2000 explorer rear which measues 59.5" wms to wms. The explorer rears housing dia.is 3.25" and they use the stronger 31 spline axles. 96 and newer have disc brakes. This rear has alot of stuff that needs cleaned off-swaybar mounts etc. to make it look better. I had to relocate the spring perches to fit my suspension. Radar
