In my quest to find one 390 may 1st 1970 rallye wheel (with no luck) I picked up a pair of august 12th 1969 15x7 wheels with original polyglas august 1969 tires still on them. My question is... I can't find the 390 part number anywhere. Are the early wheels stamp somewhere other than valve stem? Not sure how to post pics on this site anymore. Any help would be great

August 69 stamped 1970 wheels like you have there had no part number, steel and rally type.

Thanks for the help

What size are the Polyglas tires? E60s??

I have a set of 8/29/69 15x7.0"s that have the part number, but yes early ones do not have the part number.

8/12 NO
&
8/29 Yes

I also have a pair 8/12, 8/15 or 9/15 I'll have to dig them out & see how they're stamped

I have a 8/12 and it has the complete 390 number. Also a pair of 8/11 with numbers too. There are dates on the hub and inside the rim, but no other location for the 390 number other than by valve stem. At least from what I've seen.
