Schwinn Paramount -- The rear wheel spokes are loose -- need to tighten (without screwing up the true...)

The smallest spoke wrench is what fits the nipples on this bike (3.2 mm).  One of the nipples is damaged so I had to use the 3.5 mm wrench (it's rounded over...).

I put more tension on the spokes and got the wheels to spin close to true.  I used the brake pads as reference on the bike and kept adjusting LH to RH to get it close enough...

Pictures of the wheels would not be too useful in showing the condition.
