Bolt pattern 1965 Barracuda

I've got a pair on the back of one car. And I don't really like the fit, I believe it is more of a wheel problem (lug holes not so good) and I won't drive it.
I also had a set on my car when I was in my late teens 30 years ago. Drove it without mercy. As fast as it would go. Every chance the road was long enough. And I grew up rural so my cars were seeing 100+ mph every time the key turned. Not a problem with the adapters then.
I believe you just have to use a little extra care installing them and check them driving at slower speeds till your sure they are not going to loosen up.
I think those are the coolest wheels I've seen in along time.
Hope this helps. They work , just requires a careful Installation.
