The same source that supplied our original Stewart Warner 970-B Green Line tachometer.
http://67-72chevytrucks.com/vboard/s...&postcount=225 Decided to sell his beautiful SW 977-J Sidewinder tachometer, this particular tach has been converted to a modern meter by the same vendor that serviced the 970-B Green Line. It is a direct wire so no need for a monitor, it's designed to work with all ignition systems and has been upgraded with modern LED lighting. After testing this tach (btw, all our tachs read the same engine just a little bit different
) I’m thinking that this converted tach with the modern internals is the one we'll start off with.
