Wheels for Athearn cars

Need a little help! I want to replace the wheels on my Athearn rolling stock. What cars do I use 33’’ 36" 29" on?

Use 33 on most freight (ie99.9%), 36 on passanger, and 29 on some intermodal and spine cars. I use Lifelike metal proto 2000 33" smoothbacks on my freight cars, which were bty on sale last month. When in doubt compair to whar they came with, thought it truly is hard to tell any of them apart without micrometers.
