Anyone need this 70 340

The 8 digit VIN on it gives it away.

1B193352

The first digit designates the model year. In this case it is a "1" meaning 1971 model year.

The second digit is the car assembly plant. Here it is a "B" which was the Hamtramck assy plant. My 71 challenger convertible was built there.

The last six digits are the "sequence number" for the assembly plant. But two consecutive sequence numbers does not mean that the cars were built one after another in the assembly line. I believe that these numbers are assigned when they schedule the vehicle for production just before it gets "framed". They can get mixed up through the assembly process.

However, they are not necessarily begun to be built in order of the sequence number in the framing shop. It is rare that two consecutive sequence number cars are together at all on the assembly line. Once in a while it happens, but is not the "norm".

Framing is where they assemble and weld the sheet metal together.

After framing they get sent to the paint shop. If everything goes well, the car only goes aroung paint shop once...

But if the car gets a ding, fisheye, scratch, etc.. It must be sent through the paint repair loop where they fix the defect. If it gets a dent in the door or fender, they take one off of another defective body (same color) with a good part. If it is a paint flaw, they have repair guys in the paint area who are trained to repair the paint defect and blend it in. Then it gets sent to the assembly line where all the parts are assembled to the painted body. It is common for cars to get "out of sequence" in the paint shop.
