That equates to a center hole that is a tad larger than a Chevy stock rim..not by much, but enough that either you need to machine the Chevy center hole a hair, or make certain the after market wheels have the larger hole.
No fair, you know where I'm going! I happened to locate some Zeniths which would look *****in. However, I'm not in the mood to throw away money on something that "might" fit. If I do smoothies, I might as well keep the OG steelies that are on the car. I like the color on your C10, what is it called?
