71 Demon seat slides back

Hard to see but the cable I circled in this photo.

If all is well with the cable then your locks are stuck in the unlock position. (Dry and wont release back to the lock position)

Oh I see. Maybe some wd40 would loosen it? Are the seats hard to remove? Would rather keep them on, if so. Thanks for the info
