This first link will help you figure out which drive/driven gears you need. http://www.tciauto.com/tech_info/speedo_gears.htm These second two links should help you figure out your speed until you can replace the gears. http://www.prestage.com/carmath/speedo.asp http://www.prestage.com/carmath/calc_gears.asp cYa- Herb Lumpp 1966 El Camino ACES 3509, MCC 528 http://users.adelphia.net/~hlump/ ----- Original Message ----- From: "Ron Lew" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, December 18, 2002 6:12 PM Subject: [Chevelle-List] speedo off > Hey guys; > > I just changed the rear end in my 1970 Malibu.
