Based on my research, the Dexter Trailer Hub and Drum Assembly # 8-201-5 will replace the 3160121 drums on your 2003 Airstream Classic. This assembly is designed for 5,200 pound axles and features a 6 on 5-1/2 inch bolt pattern. I have attached an article on how to measure your bolt pattern so you can ensure this will be the correct fit. The hub uses # 25580 inner bearing and # LM67048. I also recommend verifying the bearings on your existing hubs so you can be sure this is a perfect match. The numbers should be stamped onto the bearings themselves.

Then for compatible electric brake assemblies, you will use the Dexter 12 Inch # 23-106 for the Right Hand and # 23-105 for the Left Hand. These use a 5 bolt mounting flange pattern.

I have attached a couple of short video demonstrations on these products for you to check out.

Thanks for the picture and info on your current brake assemblies, from that we know that the Dexter brake assembly part #23-106 that you referenced is the correct fit. For the left hand side you'd then want the part #23-105.
