The 164 is a great car. When I was in my 20's my boss gave me his 73 164e. I believe it was a GT but can't verify that a 164E GT even was built. It was a 4 speed manual with OD Round gauges with oil pressure in Paskels. Ronal aluminum wheels. Bilstein shocks. Great car. The rust bunny got it.
Last year (I AM 58 NOW) I found a beautiful 74 164e in an estate sale. I would love to find the components to make it a GT. Car is a 90 point car so I don't want to tear it apart too much.
Parts are a bitch but they do exist
