So in my trucks 11th year of life, its finally going to hit 100K. Has essentially 95,6xx on it now. Will probably hit the 100K mark in March, maybe April. Anyway, i want to start stock piling what I should have for then. things im 100% doing replace plugs - Delco iridium seem to be good choice based on the corvette forums replace wires - MSD 8.8mm worth it? or just delcos Replace serpentine belt - will make me fell better Recent things new radiator,full coollant system flush at ~80K had the trans partly rebuilt, new TC put in, full system fluid flush and change What else should i do? Shocks probably wouldnt be a bad thing. The brake lines seem to be in good enough condition. My new neighbor said every GM truck he's ever had or been aroudn needs a fuel pump aT 100K, he's a mechanic so i can get delco parts at cost, worth it? What else am I missing or should I do? blackbear it?
