Looking for manufacturing dates GRLS30

[ShortMuc]

Hi friends,

we have 2 260Z, 2+2 here in Germany, and want to know, when they have been built.
Chassis numners are
1) GRLS30 401.348
2) GRLS30 401.908

Is anybody out there who could tell me year and month of their manufacturing?
Thank you in advance

Sorry, forgot to tell:
The cars have been repainted. So the mark was removed, however not replaced :-(
The cars were exported to the European / German market; so it may be difficult to figure out the Chassis numbers in US data bases...
