Sorry, I sold the distributor on E-bay several weeks ago.  I just saw your post or I would have answered earlier.  Dan

My nephew had a 1958 Edsel Pacer 361 convertible with a  Tach drive distributor.   He has sold the car But it is owned by some one in Vernon  British Columbia!

Is it the driven gear you are looking for (the one at the end of the cable)?  If so, they may be the same as the early birds, which are available from the early bird parts suppliers.  The drive gear is in the distributor

you still have the Edsel Tach drive distributor parts?  I am in desperate need of the nylon drive gear.

I have a 58 Edsel Roundup station wagon that has a 361 engine with the factory tachometer.
While not a super rare option for the FE equipted engines it was not a big seller.
I"m sorta surprised that it never caught on with the race FE guys that wanted to use a mechanical tachometer.

The "Known Part Number" cast on the housing should be FEY 12127 A

I have had a few of them over the years. They sell for (real) in the $350.00 range.

found a photo of a 58 Edsel dash with tachometer  http://www.aarnio.com/edsel-fi/elli58/kuvat/elli76.jpg  The distributor is for a 361 Edsel with tach drive. 

I'm not that familiar with the Edsel's but I don't ever recall seeing a mechanical tach drive for an FE. powered passenger car. Possibly an option for Police package?
Edit: Just looked at some pictures of Edsel dashboards and they did have a tach.

I don't know if it's true, or applies to other cars/engines. But in about 1968 I got a 57 tach drive dizzy for my bird from an old and knowledgeable junk yard guy. He had an F code 57 bird. It came out of a junk car in his yard that was originally a police car with the optional tach. He saved it for me, and gave me time to come up with $20 for it.

I found my answer,  according to the casting code, it is for an FE engine and if from a 1958 Edsel with a tachometer.  I never realized that the Edsel had a mechanical tachometer.  It must be relatively rare as I never see one on Fee Bay.

it is large truck,most likely from the larger ys designed to work with a special carb as a govoner .not sure if it will work in the 272 -312 blocks. be carful
