66 Barracuda owners... Wheel question

I ran wheel adapters years ago. What happened to me, you don't want to happen to you. All the 7/16s wheel studs loosened up and the rear wheels began to wobble. I had to have them welded in at a Dodge dealership because I was on the road. They are not the safest. I was lucky I didn't have a wheel fall off.

I agree 100% - when I was much younger I used those things -they were NOT safe!!! They would always loosen on me. Do yourself a favor and spend a bit more money and do it right or stick with the 4" pattern.
