Another build sheet question

[jonstr]

The build date on the sheet I got from the Museum is "91/011". Is that '011' a julian date, meaning the 11th day of 1991, or is there some other meaning to the code?

If it is a julian date, is it measured from 1/1/91, or from the start of 1991 production, which I assume was some time in August 1990?

Julian date The begining of the year is the start Jan 1 1991

Also, you can confirm the approximate build date (by the month at least) by looking inside your door jamb - near the latching mechanisim, there will be a set of decals - one w/ tire pressure, the other w/ some addl. info incl. the VIN# and the month the car was built (by GM) which is what your build sheet date relates to.

I recently reviewed a Speedster Monroney label/sticker & invoice (The Callaway one) that has a build date of 1992 vs. the 1991 model year the car was listed as :cool

Thanks guys. I checked the door jamb sticker and it also says January 1991, so they match up.
