* Bolt Pattern: The number of lug nuts and the distance between them (bolt circle diameter or BCD) must match. Corvette bolt patterns have varied over the years. El Camino bolt patterns also varied by year. This is the most crucial factor.
* Wheel Offset: This determines how far the wheel mounts in or out from the hub. Incorrect offset can cause rubbing against the suspension, brakes, or bodywork.
* Wheel Diameter and Width: The wheel diameter must be compatible with the El Camino's tire size and suspension travel. Too large a diameter might rub, and too wide a wheel might require fender modifications or different tires.
* Backspacing: This is related to offset and affects how far the wheel sits inside the wheel well.
In short, you can't simply assume Corvette wheels will fit an El Camino. You must find the specifications (bolt pattern, offset, backspacing, diameter, and width) for both the Corvette wheels and the El Camino's wheel wells, and compare them carefully before attempting to install them. A wheel and tire specialist can help you determine compatibility.
