I have a used Sun tach for sale. It is in good working condition. It is a Sun tach which was optional on the 1962 Chevy Impala. It does not require a box to run it. It is model FZ-58 N. The chrome on the face has fading and some pitting. The cup has some scratches but it still presents nice. I am asking $175.00 plus shipping. I accept PayPal to family and friend only. I accept MO as well. Please send me a pm with any questions. Thank you.
