The Trailer Idler Hub Assembly for 3,500-lb Axles # 84545BX should work for you based on the information you gave, though you can make absolutely sure by using a digital caliper and measure your spindle to the thousandths of an inch where the outer bearing and grease seal ride.

You can use the photo I've attached to see exactly where you need to measure. If you get a 1.063" measurement where the outer bearing rides and 1.719" where the grease seal rides then Idler Hub # 84545BX will fit.
