Technical Help identify these spindles,race car or?

need help identifying these older spindles on my willys gasser. The bolt pattern for the brakes are 3-1/4 “ across top and 2” top to bottom bolts. Spindle is 4-1/2” from threads to inner seal. Uses a .750” I.d. outer bearing and 2.00” i.d. Inner bearing. Currently has hurst airheart brakes on it that don’t work. Would like to adapt a different set of front disc brakes on it.

 

They look like Willys spindles to me and I believe the 2" dimension you gave is where the seal rides. The step just before that is where the bearing goes.

I'd say your Willys has Willys spindles .
