On to the next issue; Apparently someone in the past of this vehicle's
ownership has removed the passenger seat and the entire swivel base to what
I can only assume,was to access the battery compartment. In doing so I
don't think all components have been replaced on the base plate,once the
swivel and seat were re-installed as this seat is extremely wobbly. It
appears to be that the wobble is emanating from the  base swivel plate
which seem's to be the culprit of the wobbly seat syndrome.

 Question; are there any other components underneath that swivel base that
are missing? The only components there are  the 4 evenly spaced plastic
spacers attached to the base plate? Even without the seat replaced on the
track this base is very loose once it is re-bolted down with the locking
nuts ?

Again much thanks to all. DS
