Ah, the Keltari. That's a rough set up even with other armies. I had to deal with it on the Nyss Hunters and the Necron Warriors. I just toughed them out in both cases, but someone recommended the "helping hands" with alligator clips used for electronic work to keep the pieces together while the glue dries.

Mostly just sitting the shoulder pads right so it looked right. The models on the bottom could be a little wavy so fitting them right sometimes was a challenge. But that was on the Cataphract side, not the Praetorian.
