I have three of them now...
First one I used to replace my housing (speedo was mechanical)came from Pete's Auto Salvage (
http://www.petesauto.net)in Jenison; second was a mechanical from 6-Mile Auto on Alpine and 6 mile (couldn't use that one at all. live and learn); and the 3rd *and final* one I snatched the gears from was electronic and it was from Baker Auto on Alpine.
