My buddy has a set of SBP slots that he just took off of his 64 barracuda. HE'S on FABO AS @64mopar. I sent him a link to your thread but you might want to pm him as well. If I remember correctly they have new tires on them as well.
Still have not heard from your buddy about the wheels he took off his car. I did try to pm him, not sure if he got it. Going to try again later today after work.
