1957 Thunderbird FEJ-12127-A2 tach-drive distributor in excellent condition; looks good and functions as it should. It can also be used to replace the vacuum-advance-only 55-56 Loadomatic distributor. If you want to retain your 55-56 Holley 4000 "Teapot" carburetor, Ted's site (eatonbalancing.com) contains a "How to" article for modifying the Teapot carb to work with the 57-up dual-advance distributors. Price is firm at $700. 

I'm located in Lodi, CA, about 35 miles south of Sacramento.
