ID:	1812904 Hi friends—can anyone help me identify this? A friend sold it to me as a tachometer drive unit for a 56J (1956 Golden Hawk), but according to Brent Hagen it is not. He says it measures out to fit some kind of a V8, but probably not a Studebaker. It is NOS and probably valuable to someone, once it’s application is determined... could Brent be wrong? (naaahh...)

      Possibly from an aftermarket Stewart-Warner tachometer set up, for a non-Studebaker/Packard vehicle?

        Looking to sell it? If so, how much are you asking?

          Autolite and Delco manufactured most of the distributors. Stewart-Warner made tachometer drives for both. The '56J came with an Autolite, but it's not unusual to find a Delco in there. What is the inside diameter and outside diameter of your tach drive?

            I'm the culprit who sold Kenny the sending unit. It had been in my stash for forty years. I knew it was not Speedster, and was pretty sure that it was not later Hawk, so when I was told that is was 56 Golden Hawk I believed it. I told Kenny that if it turned out to be something other then what I had been told it was that I would take it back.

                  According to a 1958 Stewart Warner catalog the 762-K sending unit (called a sending switch by Stewart Warner) fits Delco Remy V8 except "high tower" (whatever that is)
                  Here is a link to the catalog. (post #290) where I found the info

                      It's not anything that was ever used in a 56J, is it? I am curious, surely someone here must know?

                      Well Jack, it sounds like, if he has a line on one of these "not unusual" Delcos? Kenney could use it, in his '56J, with this Drive unit to get a working tach?
                      Or, am I missing something?

                        Since Delco made distributors for most GMs, Studes, Packards, et al, the only way to know for certain is to get a Packard V8 Delco distributor and see if it fits.

                          Looking at the rotor mount, it appears to be for a Delco distributor. But Delcos were installed on just about every American made car, if I am not mistaken.

                            If it fits a Delco V8 distributor, what are the chances it would work in a Speedster? I am looking for a working sending unit for a Speedster.

                              Yes, most GM, Studebaker, Checker, et al; but Joe, I've never seen a Delco on a FoMoCo or Mopar.

                              If it fits a Delco V8 distributor, what are the chances it would work in a Speedster? I am looking for a working sending unit for a Speedster.
                              Yes, No, Maybe. The sending unit is not voltage sensitive, so if it matches the Studebaker Delco cap diameter, you should be good to go. However, there are GM Delco which are different diameter than Stude Delco.
