There will be an up coming 70-71 speedometer sale within a week

I spent today working on an upcoming 70-71 speedometer sale. I'm going to be selling everything possible in 70-71 speedo clusters, temp gauges, fuel gauges, and speedo heads, backing covers, electrical grid... everything!
The one thing I noticed that there is a difference in the speedometers between a 70 and 71. I always thought that they were the same. It's very slight, but there is a difference. More to follow with very extensive pictures.
Only two followers, but ya gotta start somewhere. Thanks for joining, and I look forward to where this takes us and our cars.
