Re-uploading the Voice lines Ragox added to Mainland and I unfortunately had to remove. Ragox, thank you for your efforts, unfortunately it didn't quite pan out the way it should have.
The in_strong_corr#_0# is missing these two pieces: three corner pillars and two corner pillars on oppisite sides. If these new assets had vanilla names they would be in_strong_corr4_05 and 06. These don't need strongruin variants. The vanilla meshes to base this off of are i/in_strong_corr4_01-04.nif.
