Basically Riv GS drivetrain..3.42 gears.....I guess they bought a new GS as soon as they came out and went at it. Says it was completed in late 1967.....Cool how they used the Riv gauges and even the shifter.
I like either the Riviera or the Toronado better. JMO. BTW, spel-check wanted to replace Toronado with Tomado or Coronado. I found that Tomado is Spanish for "taken."
