I had exactly the rims you are describing. Mine were Fenton R/T. I had 14x7 fronts and 14x9” rears. I dont have any great pics of them up close and i gave them to the guy , who pit them on my car when he owned it in 1977, just a few years ago. He has another 68 charger he is fixing up. But, from what i remember, they were one piece. Bolts only there for looks. But, they were hex bolts.
