Chevy 1/2ton backing place. Conversion spindle. Not just a small bearing spindle.
Those will work kind of. You will run out of thread for the second lock nut. This spindle has been turned down so you have enough thread for the lock nuts.

There are 3 styles of caliper brackets that I know of. The full circle heavy brackets. The brackets with thin tin dust shields. and the brackets with no dust shields. All work the same.
