If you read that in the other thread, that was me, lol.
As mentioned, '57 to '69 will work, but the '65 to '69 wheels would be correct for a '67. They all have a Date of "65" stamped on them.
Edit: The info above would be for stock 14 X 5 Wheels. The 14 X 6 Wagon Wheels weren't available till '61. Although as mentioned '65-'69 would be correct for your car. The later years were also a safer design.
What threw me off was "stock wheels for my 67 Impala Conv". Stock wheels were 14 X 5. The 14 X 6 would have been a special order. The only car they came stock on was the Wagon.
