This is my ERA Street car with 428 PI, Sunbursts, etc. Call me if you want to discuss. I PM'd you, not sure if you ever responded. I bought the stock ERA rear and had no problem putting these Sunburst on with NO modifications to the wheels at all. Original Sunburst were 7.5 x 15 front and rear. The original look is to have a "wide gap" in the rear wells...some love the look, some hate it. I like the look..but who am I...
