There were a few manufacturers that built wheels like these back in the day! I had a set on my car back in the day and they were made by Superior wheels
I am a fan of ALL looks if done right! I would have NO problem putting modern brakes and wheels on my 68 as long as it looked as badass as some of the cars in this post!
go to harbour freight and buy a torque wrench and torque your wheel nuts at 75 lbs and you should have no problems. I would also check to see that the wheel nuts are in fact not too long and have washers on them.
I always wanted a set back in the day but they were out of my price range. I have and always will love these wheels and think that they would look GREAT on an A body!
