The jury is out on the Odom dish for now.
I think your other dish is probably easier to work with and in better shape.
That's a trade-off with the trouble of rescuing it, so it's a decision you'll have to make.
Personally, I'd get the 8'er up 'n running and by the time I'd conquered that, this 10'er would no longer seem such an effort.
However, let's talk about the Odom:
In picture #2, & #3, you have the mount.
You can see which end of it goes on top of the pole.
The big bent threaded rod is the elevation adjust, and will probably work as-is.
Worst case, you might run some nuts onto both ends, then slip it into a vice, and give it a little nudge to straighten.
I think I'd just give it a good wire-brushing with a wire cup brush in a drill, then put on some light grease to protect it.
See the big ring in picture #4?
Note the two heavy tabs welded onto it.
One is longer than the other, and has several holes in it.
You attach the ring to the ends of the long heavy box tubing of the mount.
Probably have to examine the parts and see what needs cleaning, brushing, lubing, and maybe replacing.
This
picture on Geo-Orbit will give you a basic idea how the ring fits to the mount, and to the back side of the dish.
The ring goes on with the longer tab to the top, and you select one of the holes to set the general declination.
You motor bolts to a tab on the ring or back side of the dish, and to the short stub (box tubing) on the back of the mount.
Not finding the original LNB mounting arms is a disappointment.
However, they are easy to fabricate.
Again, this all is a job for another time, but if you break it down into little parts, none are really that substantial.
If you can find a pole, that might be a head start for the 8' dish... so look around.
