production run numbers

Did a search but could not find a lot of information on run dates . One question in particular was brought up but was not answered.
What is the acceptable relation between run dates (week) and body build date (week) ?
I have a 67 05E build with run dates on the R door of H17, L door H18, gas neck cover H15. Looks like the run dates are falling in line but are these dates within the correct range of an 05E build?
Is a 67 05E a week 21 or 22 ?

Run numbers are not something that most people are familiar with.
I don't have enough data to answer your question, but those dates do look early for 05E.

I purchased the car in 1970 from a car rental firm. Auto crossed it for 2 years ( the body was completely striped of unnecessary weight and then all GM optional equipment added) and then put it in storage where it has been ever since.
Can I expect to find run numbers on most of the sheet metal componets used to build the body ?
Is 67 05E week 22 ?

Almost every piece of metal will have the stamp - brackets, door mounting plates, etc.

 I have an earlier run 11A (66) Los. Coupe.  Right door is H 43, left door H 42.   I believe 11A would be about week 44, so mine are much closer.
