I have a 65 289 c code convert. I currently have the motor apart. Found out the motor and tranny was rebuilt. How can I decode the date code of this motor? Where can I find the rearend type? Is it possible to find out where and when it was built?
The idiot I bought this car from LOST the warranty tag :(. I would like to replace it. Is this possible or am I barking up the wrong tree? I know there is someone out there in VMF land that can help me out.

Thanks for the greatest mustang forum around.

Since you're asking several generally unrelated questions here...
The *engine* date code is actually stamped on the aluminum ID tag attached to one of the intake manifold bolts -- however, this will simply tell you the year and month of assembly. Other components will have their own casting date codes. A truly outstanding reference for reading all Ford date codes can be found at:
http://www.hammar.dyndns.org/~djhamma/datecode.htm :)

Rearend type is marked on another aluminum tag bolted to one of the rear differential bolts, though it's often buried under an inch or two of crud. The best reference for decoding them is Leon Biesiadecki's Ford Rear Axle Identification Guide, located at:
http://www.ridgenet.net/~biesiade/Fordrears.html

Now, if you meant, "How can I find out what type of rear my car was *ordered* with, because it's now missing" -- then you're probably out of luck if you can't find a legible copy of the build sheet (if you've got a Metuchen-built car, you may find one taped around the underdash wiring harness behind the dash cluster) -- detailed data such as that offered by Kevin Marti for 1967-73 cars simply isn't available for earlier years.

As for reconstructing the door tag -- that's mainly a matter of some detective work as to your original color, trim, engine, axle and transmission. Build date can be estimated using your VIN, but the DSO is pretty much anyone's guess. Once you've come up with the most likely codes, though, there's only one place to go for a near-perfect reproduction door tag -- Marti Auto Works, at:

Hope this answers some of your questions at least.

You can find the assembly date for the engine stamped into the block on a machined ear in front of the driver's side head. This date will show the day, month, year, and inspector's stamp.
