I dont see anything to adjust on the back side. How do I get the drums off?

Remove the axle nut and pull. Some EA82's had self-adjusting shoe's - if there is no adjuster then they are self adjusting and there is no need to pull the drum except to replace it or the shoes.

They have worn a groove in the drum and are binding on it. Get a big hammer. Likely some stuff will get bent and it may fly apart when it lets go.....

I think there may be a way to release the self-adjusting ratchet mechanism from the back but I don't remember exactly how it works.

havent' seen old school drums in a long time, many have two threads holes - i believe they're 8mx1.25 threaded holes. Tons of bolts all over the car fit it. But thread a bolt in there and it pushes the drum off.

Yeah, the problem is there's a small "ridge" of rusty non-smooth area of metal that has to pull over the shoes.

take the brake line off the wheel cylinder, take the two bolts out of the cylinder, find the shoe retainer pins on the back of the dust shield, pry them up and cut them off (they look like nail heads)

take the axle nut cotter out, take the (36mm) nut off, in the washer underneath put a small screwdriver in the slot, rap on it once firmly and it should pop off when it spreads

pull the drum, you may need a puller to get it started, it's rusted to the splines

or beat the crap out of it with a mallet working around the edge of the drum so it gets driven off evenly

-POP- all the guts fall out when the drum hits the dirt

if you have enough of a lip to not get the shoes off, it's probably out of limits, limit is 7mm thick

replace the shoe spring retainer pins with new ones, fresh cotter key yadda yadda

anti seize the spline shaft, try to clean the corrosion from the cone washer seat, and the cone washer, some anti seize in the cone seat is very nice the next time you have to do this
