A few weeks ago there was a thread about small
plastic clips used on the front seat swivals.
I recently cut 2 of these out of a camper and
the swivals I have do not have these.  There is no
holes to install these plastic clips, and it looks like
this is a different design?  Anyone have any Idea
as to what's up here?  Designs change?  Are these
still worth using?
