Thanks to 68tpls400 for giving me a heads up on 2 HG wheels which I purchased. They apparently came from a Sprint car. After getting them home, I noticed that one of the areas between 2 of the lug holes says "GM" with "65" below it. For what does the "65" stand? I assume it is not the year. Is it the last 2 digits of the part number?

I also purchased a good front bumper core. It has "Made in Canada" on one of the top mounting tabs like many of the other original bumpers.

Thanks
