SW 990b Tach Sender - NOS
 

Selling my last 990b sender for 970/977 Pedestal tachs. I bought a bunch of Day 2 parts for a car that I was pursuing, but ended up not buying the car. This sender is NOS but I can't find the box. Still have the manila envelope with the mounting screws. I think it is dated 1968 or 1969 on the back. $225 shipped anywhere in the US.
