Anyone out there know what these are?
I bought these years ago for my old Datsun 1600 Roadster and they didnt fit
and forgot I had them in the attic. I believe I was told they may have been
from a 240 260 or 280 Z the serial number (?) is an upside down U and the
numbers 3 13 80 1
how many do you have they look like wheel rims
i have all four
