Steve, in '67 most of the Camaro competitors just added a factory style traction arm on the driver's side to go along with the stock one
that was already there on the passenger side. There wasn't a whole lot of lateral location being concentrated on that first year although
a factory built rear sway bar arrangement was made in very limited quantities and this helped lateral control somewhat. For 1968 and
later that's when you started to see some of the Panhard rods and Watts links come into play. Here on the underside of the Gary Morgan
'67 Z-28, you can see a Panhard rod installed in conjunction with the two factory style traction arms. It is generally thought that the
traction arms caused suspension bind but Gary Morgan always ran the car in this configuration from '67-'69 and he said it worked well.
Gary held the A/Sedan track record at Watkins Glen with this car back in the day. The pictures below are from when the car was being
sold by RK Motors in Charlotte.
