Default Saturday's Ladders and Eithers

This one has two "Or" clues, one "Either" clue, and two relational clues that stand between me and the solution.

Here is the blank:

Here is where I'm stuck:

The two relational clues both have exact measurements. This would normally be good, but neither of these clues have values that have available substitutions.

Clues 7 and 8 both mention the same value "Ereph". But there is no linking value on the other side of the OR statement. When I map out all the combinations of these, I don't have any eliminations. That is, all the combinations are available.

I thought of a relationship between clue 5 and clue 9. Clue 9 shows the relationship between EX53 and PL120. It occured to me that Clue 5 shows two potential equivalent values for EX53. If either of these could not match the relationship to PL120, then that would be the elimination. But no. No eliminations can be found.

I've looked for all my usual oversights. I've looked around the corners, looked for complementary exclusion sets, 2x2 sets, but nothing.

At this point in the puzzle, I only have one group of equivalencies: 49LightYears = 650,000 == MKP427. But there are no remaining clues that use any of these values. So I cannot make any substitutions.

I'm hoping there's some technique I have yet to learn for this. I'd hate to find out I've missed something I've already learned.
