I have a tach mounted on the steering column. It's 10,000 rpm and the name on it is Dixco. Original?

Nope.

Dixco tachs were the 'cheepo' tachs used in the 60's. "Real car guys" had Sun tachs and scorned those who had Dixco tachs. Now, they are pretty desireable,esp among the Rat Rod group. Check them on Ebay.

A 67 would have what is called a blinker tach, it mounted where it covered up your turn signal light on the dash, so the turn signal light was mounted in the tach. Do a search on Blinker Tachs, they only came on 67's.
