Here's a tri-five doing its thing notice the wipers my first 68 Javelin used to do this at speed and the tops of the front side windows would pop out .
After school I had a 68 Rebel SST 343 4 speed posi with 2 something very tall hiway gears was a fun car bench seat that would fold flat like a bed, came in very handy when driving and you needed to take a nap
