| Thanks, Mark.
|
| I tried it and it works.

| If anyone needs a replacement transducer take note of the following
| number: Checker Auto #36-102 ($60.99 plus core). Checker lists this one
| for the '76 Caddy Eldorado and the number cross references to GMC #2503
| 0712, the number shown in GMC dealer's computer as the successor for the
| one listed in our GMC Motorhome parts manual.
|
| The AC/Delco rebuilds have been discontinued. Cinnabar also says they
| are unable to get rebuilds, so I was happy to find one at Checker. It's
| rebuilt by A1-Cardone.
