The vin is stamped into the frame

Most likely the engine number is XXXXX they used for the VIN. Not at all uncommon.

the VIN as the serial number off the Y-block

The engine number on an A is the same as the one stamped in the frame. Model A's shared running gear on a lot of models. The frames came down the assembly line, The engines were put in and the engine number stamped in the frame.

Use the engine number, the title number is XXXXX that, the number on the title assigned to that title by the state, not a number assigned to the car.

on the engine if it is the original one and on the frame, drivers side right behind the first body mount hole. you can not see it with the body on

Vin on a 29 is usually located on the drivers side frame rail , very near where the 2 bolts that secure the cowl post to the frame bracket are ( area between the cowl post with hinges and the firewall) All of mine have been preceeded with a ''star" then an ''A", then the number , and then another star after the number. Also I have seen them near where the battery is located on top of the center crossmember. If you find the number and can't quite make it out, you can look just above the split flange of the firewall on the drivers side, there should should be a total date of manufacturing (month, day and year ) stamped in the top section very near the split flange.

Some Model A's have a body number stamped on the first cross brace on the body(right in front of the seat) All this number does is tells where it was built and the sequential number.

The frame number is XXXXX best bet for determining the orig.

A lot of correct answers here. The VIN is stamped on top the frame under the body and can't be seen without removing the body, how convenient, right?

Where can I find the chassis number or Vehicle Identification Number on the Model A Frame?

When the Model A was being assembled at the Ford plant, after the new engine was lowered into the chassis, a worker would stamp that engine number on top of the frame, left side, just back from the front body bolt hole (approximately where your left foot would rest inside the car.) Unfortunately, on a completed car, the number cannot be seen because the body webbing and running board splash apron is on top of it.

If you're lucky enough to have the body off the frame, find the front-most body bolt hole on the left side of the frame and clean a 12" section to the rear of that hole. Many years of dirt and grime and rust may have accumulated in that area, so some gentle scraping and cleaning may reveal the number. Don't be surprised if the number doesn't match the current engine number in the vehicle. It was common practice in the 1930s and 1940s to replace rather than rebuild Model A engines.
