Dear Chandra, where at APS did you collect? NE-CAT (and in particular beamline 24-ID-E) is well set-up for long unit cells. You could ask Yury Polikanov ( https://bios.uic.edu/profiles/polikanov-yury/) for advice. He crystallizes ribosomes with unit cell that are not quite as big as what you have, but quite big nevertheless.
An alternative would be P14 at EMBL. They have measured crystals with unit cell dimensions beyond 1 kÅ. All best.
