17's on my 67

The boyds are (supposedly) available in a 17x7 also. I would recommend them for the front.
I would also check (by phone!) with Extreme Customs. They list the polished version on their website at about $30 less each than summit.
The question is always AVAILABILITY! Thats why i recommend an actual phone call, talking to a human.
Edit. I have a 67 barracuda too. If you get them i would love to know how they fit, and do you like em.
