Hey Jeff, thanks for the pictures! I found a break down of your axle online and yours is a a 3,500 lb axle, which uses a # 84 spindle compatible with a # L68149 inner and an # L44649 outer bearing. Pretty sure you need the #84 E-Z Lube Spindle item # TRU77FR but I would like you to take some measurements to confirm because I could not pull a part number.
The diagram I found matches up to the #84 E-Z Lube Spindle w/ Brake Flange item # TRU77FR. It has a 3" inner diameter and the Stub dimensions are 3-1/8" diameter x 1" long and an overall spindle length of 6-1/8".
I have linked a of diagram below that shows how wide the spindle is when it attaches to your Tie-down axle.
