I picked up an 85 C10 and will be lowering it. I'm not sure if it will be a 3/4 or a 5/7. I know I will be needing drop spindles, lowering springs, shock absorbers, c notch kit, and axel flip kit. Please correct me if I'm wrong. Will I need specific control arms for a lower as well? These will be getting replaced regardless, but I'm not sure if I can stick with OE or if they need to be specific for lowering. Thank you.
