I'm a little puzzled.  I removed the driver's seat and the swivel
assembly from my '90 Westy and find underneath the rails for mounting
the seat without the swivel assembly.  I've seen several pictures from
other list members that seem to show this last part (the fixed, no
swivel seat rails) removed giving access to the shallow compartment
underneath, but I can't see any way to remove the pan in the middle.  Is
this welded in or is there a way to get it out?
BTW, for those of us that are taller and have trouble seeing the
speedometer  and tach I'll bet that mounting the drivers seat on the
lower set of rails (eliminating the swivel base) would help.
