Thanks- I did find some some posts. One thing I just realized is that this is a Huck Brake: Adjusters are at top! And just a thin metal flap over holes. Anyhow, I was initially thinking- ‘No adjusters’ since I saw no access slots at bottom.
So - this Huck Brake new to me. Going out now to back off adjusters. I’m posting a pic. RA

This diagram will help you 'back off' the Huck adjusters. Also, I encountered the same type of problem a number of years ago on a 1972 C10. Here's a (THREAD) with a number of good ideas for removing rusted brake drums.
Good News: I removed the huge rear drum from my 3/4 ton ‘53. Here’s how I did it: 1) Removed wheel cylinder bolts and pushed on unit through openings in rear brake plate. ( actually used long bar and hammer ) 2) Using 2 lb hammer I repeatedly hit sides of drum until it started to move. Some of these blows were glancing so as to add a turning force.
Note: I tried Unsuccessfully backing off Star wheels - very difficult access and these were stuck. No movement here. Use goggles and don’t crack your drum.
