The range of trailer spindles we offer is shown on the linked page. These include both round and square stub types rated for axles ranging from 2,000 lbs to 7,000 lbs. On the chart you can see the key dimensions for five points on the spindle, including where the grease seal rides (B) and where the bearings ride (C and D).
Spindle dimensions must be taken with precision, to the nearest few thousandths of an inch; fractional dimensions are not accurate enough so you will want to use a precision caliper that will measure to the nearest thousandth of an inch.
The TruRyde #84 spindle, part # TRU47FR is designed for use with 3,500 lb axles. It has a 1-1/2" square stub, measures 8-1/4" in overall length and uses a 1.378" ID inner bearing, 1.063" ID outer bearing, and a grease seal with an ID of 1.719". If the caliper readings of your spindle measurements match, then this would be the appropriate choice.
