I'd guess the s-10 is too narrow and the 70 and up camaro is too wide, but I'll bet the trackwidth of a 78-90 GM midsize chassis is probably just about right. These are coil suspended in the rear, came with v-8 worthy rears with good ratios and power steering and front disc. The framerails are a lightweight c-channel and are parallell and straight for easy lengthening or shortening.
