Question:
I have a hub that is cast with the number pt581750. I was wandering if you could pull up that number and tell me what spindle goes with it. I have a bad axle and plan to build my own instead of buying one. Thanks

From what I could find about your hub, you need the #84 spindle like # TRU84FR which is a round spindle. A more accurate way to figure out the needed spindle size is to first find out the measurements of your bearings. You can also measure the spindles on your damaged axle and match them to the inner diameter of the bearings that fit a #84 spindle.
The matching bearing kit is Bearing Kit for #84 Spindle # BK2-100. This matches L44649/L68149 Bearings which is what I believe your hub uses, but double-check with some measurements to be sure.
