Date of Manufacture on 6J x 16 Fuchs

[Hoyarunner]

I have a set of 6J x 16 Fuchs (Part# 911.362.113.00), which are the later 6J x 16s that were on 1985-89 911. Unlike the earlier Fuchs, such as the 6J x 15s and 7J x 15s, there is no distinct month/year of manufacture code, such as "10/70" for October 1970 or "4285" for the 42nd week in 1985. On the inside of each wheel, there is a raised box on one of the petals that is stamped "161." Is that the date of manufacture? None of the other stampings make any sense for a wheel that should have been manufactured between 1985 and 1989. Does "161" stand for the 161st month during the production run from 1985-89. I'm at a loss to figure out the date of manufacture on these two 6J x 16 Fuchs. Please help!

Color me curious but why do you want to know dates on a 6x16?

Please do not tell me date match goofiness has trickled down to 3.2 cars?

Apparently it has. There is a Classified Ad on PCA's weekly E-Porsche Newsletter by a guy who is looking for, and I quote, "...two Fuchs 6J x 16 wheels for 911 Carrera (911.362.113.00) with a date stamp in 1988 no later than week 40." I just happen to have two 6J x 16s off a Carrera, but don't understand the way the date of manufacture codes work on these more recent Fuchs. I understand the date of manufacture codes on the earlier 6J x 15s and 7J x 15s, but not the 6J x 16s. If you can help explain it, maybe I can help out a fellow Porsche owner, who--yes--is being a little extreme. I'm not judging; just trying to help.
