The spindle you would need based on the dimensions you provided is what is referred to as a #42 spindle. The part # TRU37FR would fit and has a 5 bolt mounting flange for the brake assemblies.

These have a 2,600 lb capacity per spindle.

I attached a review video for you to check out as well as a picture that has all of the dimensions of the spindle listed.
