body shop lost his tags and the rear trunk floor has been replaced. Thought that there was somewhere on the site with numbers and build dates but could not find it

Made a quick and simple chassis number decoder.
Porsche 914 chassis number decoder


If anyone has any issues with it let me know and I can modify it. Appears to work correctly for my 1974 (IMG:style_emoticons/default/smile.gif)

@914Wes Tried with my 1973 and didn't work. (IMG:style_emoticons/default/sad.gif)

Line 11 is incorrect.

The 95 will roll over to a 96 if there were more than 99 cars made that day.

So your daily_sequence should be computed as:

CODE

roll_over = int(chassis_number[3:5])
daily_sequence = int(chassis_number[5:7]) + ((roll_over - 95) * 100)

Few more issues with the online decoder above

- The chassis for a certain model year were built the previous year
- The week number calculation assumes weeks always start on January 1st but they actually start on the first Monday of the year.


So in the example of a '73 car with chassis number 2449628 the answer should be:
Thursday, June 15th 1972

instead of
Thursday, June 14th 1973

I'll work on correcting the script once I get back from Okteenerfest. Thanks for the input.
