The plot thickens.
The 1803 rear drum/hub assembly sample at Max Merritt for 351423 matches the one sent by the flackmaster. 2" shoes are correct for the 1803.

According to the book, the 1803 and the 1806 share the same hub/drum assembly.

There's a logical syllogism here that would tell me what hub/drum assembly is on my car. (Where is Guscha?) My shoes are 2" supposedly correct for an 1803. The drum depth on my drum and the flackmaster's drum both measure 2-9/16".

The inside diameter is a full 1/8" bigger on my hub.

The only larger axle, and therefor larger hub hole, is the ambulance one, which takes larger shoes.

But it seems a 2-9/16 depth drum would accommodate shoes larger than 2". Is it possible I have an ambulance axle and ambulance hub/drum, but 1803 differential/ axle housing and brake backing plates and shoes?

I have a vague recollection that my axle was changed in the 1970s. I will check with that person, who for the moment will remain anonymous and see if he remembers anything about this.

It might be a good idea to record the specs on these hub and drum for the future.
