I'm commenting only to say I enjoyed the story. I learned something new. I will also keep an eye out for flush-mount Cadillac headlamps when I go to junkyards. Kudos to Sajeev and Jack, two of my Hagerty favorites. And I just made $8300 on your employer's IPO.
If it's necessary to leave a personal opinion, I'll just say the wheels aren't my thing. Neither are BMWs but I read those articles as well. In fact, if I could return the cars to stock condition, I'd prefer them over much of what the angriest commenters probably own. I can guarantee no one in this article is my worst enemy, nor the hobby's worst enemy. So I'll save my vitriol for nameless, faceless string-pullers who would prefer that I "own nothing and be happy".
