Arm rest removal in an 89 Suburban (bucket seat arm rests)

[77c10diesel]

I have an 89 Suburban that the arm rests( on the bucket seats) are getting a little worn, not the covers, but the foam. I want to remove the arm rests to redo the foam inside, but I can not figure out how to get the arm rests off. I can see that there is a screw in the top at the pivot, but it only seems to control the angle of the arm rest, or the stop position. Is there a clip, or screw that I am missing?
