Given the measurements you provided, there are three spindles we offer for a 3,500-lb axle:

#84 Spindle - 1-3/4" Diameter (8-1/4" OAL) 1,750 lbs part # TRU64FR
#84 EZ Lube Spindle 1-3/4" Diameter (9" OAL) 1,750 lbs part # TRU74FR
#84 Spindle - 1-3/4" Diameter (11-1/4" OAL) 1,750 lbs part # TRU84FR

The bearing surfaces of each of the three are the same, with the difference being the overall length of the spindle.

I would recommend using a digital caliper and comparing the bearing surfaces shown in the diagram on each product page to the existing spindle.

All three spindles are for use with:
Inner bearing: L68149 (1.378" inner diameter)
Outer bearing: L44649 (1.063" inner diameter)
