Jack's Comments:

This is the newest and best reproduction Dearborn radiator cap available on the market today.

We have compared this new cap to the last reproduction, and you can see it's very different. This new cap is so close to the original that it will be difficult to distinguish from a production Autolite Dearborn cap. See an example of an original production cap in the next-to-last picture.

Concours Notes:
The Dearborn Autolite radiator cap came on all 1969-70 Ford/Mercury cars, BOSS 302's and BOSS 429's built at the Dearborn Michigan plant. The only exception is 390, 428 Cobra Jet cars with chrome valve covers and GT350/GT500 Shelby. Note that it's considered more correct for 1969-70 Shelbys to have the chrome Autolite cap, but the Dearborn cap is also acceptable by some judges. 

This is one of several parts that are considered plant-specific. Ford had several vendors for each common critical part, and sometimes the vendor closest to the plant became that plant's sole supplier if they were able to keep up with that plant's needs. Originals are nearly impossible to locate and are crazy expensive. When we have found originals in good condition, we have sold them between $500-$650 after restoration (mostly to BOSS 429 customers).
