76' K-10 Stepside Need Some Help?

[dragonball98312]

Hi i know this thread is nice and dead but i have some questions. I just picked up a 75 cheyenne k10 stepside and ive been curious about the strip package it has. Unfortunately it no longer has its spid sheet. I see alot of info about the 76 sport trucks. My truck looks identical to them with only a few differences. Its a 75 for one, its a cheyenne not a Scottsdale and the list doesnt show green as an available color. Was the sports truck an option in 75? Im actually in the process of converting it to 2wd and lowering it
