Professional rebuilt AC Delco units. When your truck has a 235 or V-8 installed and you are needing your temp gauge to read 220 and your oil to be 60 lbs, then this is the gauge you will need. We do not sell the non rebuild-able reproductions sometimes on the market. This includes new odometer, needle, face decal, new chrome bezel, as appropriate. Other items cleaned and rebuilt. Top quality! (Attaches to original square end type cable) Must have your core before we ship. NO exceptions!! Hand built in the USA. HERE IS OUR RECORD ON SPEEDOMETERS: Since the year 2000, we have sold 2,000 rebuilt General Motors speedometers (1934-1966) Maybe one return. ALL from the same builder! GOOD NEWS! We usually keep one assembly in stock for the 235 six cylinder engine, so you receive fast turn around.
