Finding 4R OEM numbers

[setterpet]

A newbe. I have to replace my 4R '03 transfer case? Its because of the typical o ring leak at the actuator. I can buy a replacement transfer case from an 05 with 45000 miles for $500. But I am concerned that I am getting the right one. My dealer was not very forthcoming with the numbers to confirm I have the right TC. Any suggestions on how I can get those numbers?Any suggestions on how I confirm this might be the right TC? THX

What Trim/Options is your '03?

Limited, V8 Auto Trans 4WD

It should be the same transfer case across all the 4th Gen years for the V8.
I will double check tomorrow at work.
