71 Dually - you say "This post contains a lot of details, information and methodology. I do hope it is not to convoluted or difficult to understand." It is a great post for me and completely understandable. I had already done the whole spid and doorplate info routine and now will go to the number on the backing plate (had no idea that it is there and even a look through the dirt/dust didn't reveal anything when I crawled under there yesterday).

special-K - thanks for your post - that logic is right on the mark.

I think that the biggest problem here is a visual memory from the last time I had one of my C30 axle/drum setups apart. In my mind I am seeing that big finned drum up on the bench while I was installing the new seal and the wider brake shoes from which I cleaned the lube - but - when I consider the tag data and read your comments, am thinking that vision must be a figment of my imagination. I do try to learn as much as possible and remember details every time I do some repair like this, but old age must be setting in.

Due to distance/time factors, have been stubborn about wanting all replacement parts in hand before I tear down. But, am thinking it best to go out there and get it apart even though it will sit in an undesirable place for a while.

You all have been most gracious and helpful - definitely will post the outcomes here. Thanks.
