Hey Jesse. The Terran Axle Trailer Idler Hub Assembly for 5,200 to 6,000 lbs Axle - 6 on 5-1/2 item # TX43VJ is indeed compatible with the #42 Spindle for 5,200-lb to 7,000-lb Trailer Axles - 2-1/4" Diameter item # TRU57FR. Both of these parts are sold individually.
Manufacturers don't give out CAD files because they don't people making their own parts. I have attached a diagram of the #42 Spindle item # TRU57FR below.
What kind of trailer do you have?
